Beirut blast one of largest non-nuclear explosions in history, says UK university study

  • More than 190 people killed in the Aug. 4 tragedy

LONDON: The Beirut port disaster was one of the largest non-nuclear explosions ever recorded, according to a UK university study.

The devastating blast yielded the equivalent of between 500 and 1,100 tons of TNT, researchers from Sheffield University’s Civil and Structural Engineering department said.

The report put the blast, which tore through the Lebanese capital and killed more than 190 people on Aug. 4, at one-twentieth the strength of the atomic bomb dropped on Hiroshima in 1945, which was in the range of 13-15 kilotons of TNT equivalent.

The study, by the university’s Blast and Impact Engineering Research Group, was published in the journal Shock Waves. It used videos and imagery from social media to determine how the explosion’s shockwave flew across Beirut and the impact it left in its wake.

“The Beirut explosion is interesting because it sits almost directly in a sort of no-man’s land between the largest conventional weapons and nuclear weapons,” Dr. Sam Rigby, from the research group, told BBC News. “It was about 10 times bigger than the biggest conventional weapon, and 10 to 20 times smaller than the early nuclear weapons.”

Judging by the study’s findings, the Beirut blast was in the top 10 in terms of the most powerful accidental man-made explosions in history, Rigby added. “Beirut’s certainly the most powerful non-nuclear explosion of the 21st century.”

The group hopes its findings can assist emergency planners deal better with similar disasters in the future, with data assisting first responders to help predict the nature of injuries and any structural damage at various distances from a blast.

“The disaster that hit Beirut this summer was devastating and we hope that nothing like that ever happens again. This was an unprecedented event because never before has such a large explosion been so well-documented,” Rigby said. “The reason why we decided to analyse the explosion is because, as engineers, it’s our job to use the skills and resources we have at our disposal to solve problems and ultimately to help people.

“After seeing the events unfold, we wanted to use our expertise in blast engineering to help understand what had happened in Beirut and provide data that could be used to help prepare for, and save lives in such events should they ever happen again.

“By understanding more about the power of large-scale accidental explosions like the one that occurred in Beirut, we can develop more accurate predictions of how different buildings will be affected, and the types of injuries there are likely to be at different distances from the blast.”

Investigations into the disaster determined that the explosion was the result of an accidental detonation of nearly three kilotons of ammonium nitrate, which had been stored without proper safety measures in one of the port’s warehouses since 2014.

The blast also injured more than 6,500 people.

“Think of it like a kid on a swing,” Rigby said. “If you push the child and see how far they go, you can then work out how hard the push was. That's essentially how we work out the yield.

“When we know what the yield is from these sorts of events, we can then work out the loading that comes from that. And that tells us how to construct buildings that are more resilient. Even things like glazing. In Beirut, glazing damage was reported up 10 km away from the center of the explosion, and we know falling glass causes a lot of injuries.”

According to the study, the explosion released the equivalent of around 1GWh of energy in milliseconds, which is equal to the hourly energy generated by three million solar panels or 400 wind turbines — enough to power 100 homes for a year.

Iranian combat drone crashes into restaurant in Jordan’s capital, Amman

  • Jordanian army says the Shahed 101 device had an explosive warhead but it did not detonate on impact
  • Residential buildings in Abu Nseir and Azraq were recently hit, and 27 intact drones with explosive payloads crashed in uninhabited parts of the country

LONDON: An Iranian Shahed 101 combat drone crashed into a building in the Umm Uthaina area of Jordan’s capital, Amman, on Monday.

Brig. Gen. Mustafa Hyari, a spokesperson for the Jordanian army, said the drone had an explosive warhead but did not detonate on impact when it hit the patio of a restaurant in Umm Uthaina. There were no injuries and military engineers dismantled the device.

Recently, two drones struck residential buildings in Abu Nseir and Azraq, he said, and 27 intact drones with explosive payloads crashed in uninhabited parts of the country. In addition, hundreds of drone and missile parts fell onto Jordanian territory, Hyari added, but did not cause significant damage or serious injuries. He urged Jordanians to seek shelter when sirens sound, the Jordan News Agency reported.

Tensions have been rising in the region since a conflict between Israel and Iran began on June 13, sparking fears of a full-scale war across the Middle East. The two countries have continued to exchange attacks since then, and the situation escalated on Sunday when the US carried out airstrikes on three Iranian nuclear sites.

Iran confirms missile attacks on US bases in Qatar and Iraq

  • Qatar condemned attack, calling it “flagrant violation” of sovereignty
  • UAE “closely monitoring ongoing regional developments” and “continuously assessing the situation”

DOHA: Iran confirmed it launched missile attacks Monday on US military bases in Qatar and Iraq, retaliating for the American bombing of its nuclear sites and escalating tensions in the volatile region, state media said.

Iran launched six missiles toward Al-Udeid Air Base in Qatar, as the sound of several explosions were heard over Doha.

The announcement was made on state television as martial music played. A caption on the screen called it “a mighty and successful response by the armed forces of Iran to America’s aggression.”

Qatar said it “successfully intercepted” missiles targeting the US base, and added it reserved the right to respond directly and in accordance with international law following the strikes.

It said it condemned the attack, calling it a “flagrant violation” of its sovereignty.

“We express the State of Qatar’s strong condemnation of the attack on Al-Udeid Air Base by the Iranian Revolutionary Guard Corps, and consider it a flagrant violation of the State of Qatar’s sovereignty and airspace, as well as of international law,” foreign ministry spokesman Majed Al-Ansari said in a statement.

The Gulf nation had announced earlier Monday it had closed its air space temporarily to ensure the safety of residents and visitors. Also on Monday, the US embassy in Qatar had advised Americans to shelter in place, out of what it said was “an abundance of caution.”

“The White House and the Department of Defense are aware of, and closely monitoring, potential threats to Al-Udeid Air Base in Qatar,” a senior White House official said.

The UAE is closely monitoring the ongoing regional developments and is continuously assessing the situation, a government spokesperson said.

“This approach froms part of the UAE's interegrated national framework for emergency and crisis management, which prioritizses public safety and the continuity of operations across all sectors,” the spokesperson added. 

UAE airspace had also been closed, according to flight path data and air traffic control audio cited by FlightRadar.

Bahrain said sirens sounded in Manama with citizens and residents urged to remain calm and head to nearest safe place, according to an Interior Ministry post on X. It also suspended air traffic temporarily on Monday.

“The Civil Aviation Affairs of the Ministry of Transportation and Telecommunications announced the temporary suspension of air navigation in the skies of the Kingdom of Bahrain as a precautionary measure in light of recent regional developments,” said a statement carried by the official Bahrain News Agency.

Kuwait Airways, in a post on X, said departure flights had been suspended due to the regional developments.

European Commission allocates $230 million to support Palestinians

  • UNRWA to receive €52 million ($58 million) to support its education, healthcare, and relief services for Palestinian refugees
  • Dubravka Suica, commissioner for the Mediterranean, said: ‘Our support to the Palestinian people remains steadfast’

LONDON: The European Commission announced on Monday that it has allocated $230 million to support the UN Relief and Works Agency for Palestine Refugees in the Near East and the Palestinian Authority.

On Monday, the commission announced that it had allocated €150 million ($172 million) to the PA to ensure the delivery of essential public services, including payment of salaries for teachers, civil servants, and healthcare workers. This financial support is contingent upon the implementation of the reform agenda, it added.

UNRWA received €52 million ($58 million) to support its education, healthcare, and relief services for Palestinian refugees in the Gaza Strip, West Bank, Jordan, Lebanon, and Syria. Since late 2023, UNRWA has been crucial in providing aid and shelter to millions of Palestinians in Gaza amid ongoing Israeli attacks, some of which targeted UN staff and UNRWA facilities.

Dubravka Suica, the commissioner for the Mediterranean, said: “Our support to the Palestinian people remains steadfast.

“With this (first) disbursement of €202 million to the Palestinian Authority and the UN Agency UNRWA, we reaffirm our unwavering political and financial commitment,” she added.

The funds are part of the commission’s Palestine Recovery and Resilience program for 2025-2026, amounting to up to €1.6 billion ($1.84 billion), in which the EU reaffirmed its support for the Palestinian people and its commitment to a two-state solution, as announced in April during the EU-Palestinian Authority high-level political dialogue.

“The EU is deeply concerned about the catastrophic humanitarian situation in Gaza and the worsening conditions in the West Bank. We remain firmly committed to a just and lasting peace, grounded in a negotiated two-state solution,” Suica added.

Syria interior ministry announces arrests over Damascus church attack

  • The shooting and suicide bombing Sunday at the church in the working-class Dwelaa district of the Syrian capital killed 25 people and wounded 63

DAMASCUS: Syrian leader Ahmed Al-Sharaa vowed Monday that those involved in a “heinous” suicide attack on a Damascus church would face justice, as he called for unity in the diverse, multi-faith country.

The shooting and suicide bombing Sunday at the church in the working-class Dwelaa district of the Syrian capital killed 25 people and wounded 63, the health ministry said.

Syria’s interior ministry said Monday that authorities had arrested several suspects in connection with the suicide attack, with the minister saying the operation targeted cells affiliated with the Daesh group.

A ministry statement reported the arrest of “a number of criminals involved in the attack” during a security operation near Damascus, while Interior Minister Anas Khattab said the operation targeted “positions of terrorist cells linked to the Daesh group.”

Daesh has not yet claimed the attack.

“We promise... that we will work night and day, mobilizing all our specialized security agencies, to capture all those who participated in and planned this heinous crime and bring them to justice,” interim President Sharaa said in a statement.

The attack follows incidents of sectarian violence in recent months, with security one of the greatest challenges for the new authorities.

The attack “reminds us of the importance of solidarity, and unity of the government and the people in facing all that threatens our nation’s security and stability,” Sharaa said.

The spokesman for Antonio Guterres said the UN Secretary-General strongly condemned the attack and expressed his “deepest condolences” to the families of the victims and wishes a swift recovery to those injured.

He added that Guterres said that all perpetrators of terrorism must be held accountable, and called for a full investigation.

“The Secretary-General reaffirms the commitment of the United Nations to supporting the Syrian people in their pursuit of peace, dignity, and justice,” the statement added.

The attack was the first suicide bombing in a church in Syria since the country’s civil war erupted in 2011, according to the Syrian Observatory for Human Rights monitor.

It was also the first attack of its kind in the Syrian capital since Assad’s ouster.

A prayer service at the church is scheduled for 6:00 p.m. (1500 GMT).

Since the new authorities took power, the international community has repeatedly urged them to protect minorities and ensure their participation in Syria’s transition, particularly after the recent violence.

Interior ministry spokesman Noureddine Al-Baba said Sunday that “the security of places of worship is a red line, and all efforts will be made to ensure people’s freedom to perform their religious rites.”Daesh “aims to sow sectarian division and incite all components of Syrian society to take up arms, seeking to show that the Syrian state is unable to protect its communities and citizens,” he told a press conference.

The top cleric of Syria’s Sunni Muslim majority, Grand Mufti Osama Al-Rifai, condemned acts of violence and terrorism in a statement Monday.

“We express our complete rejection of targeting places of worship and terrorizing believers,” he said.

Foreign condemnation of the attack continued to roll in on Monday.

President Recep Tayyip Erdogan said Turkiye would not allow extremists to drag Syria back into chaos and instability, vowing that Turkiye would “continue to support the Syrian government’s fight against terrorism.”

Turkiye, which is close to the new authorities, has repeatedly offered its operational and military support to fight Daesh and other militant threats.

French President Emmanuel Macron also denounced the “horrible” attack, while the EU said it “stands in solidarity” with Syria in combating ethnic and religious violence.

“It is a grave reminder of the need to intensify efforts against the terrorist threat and to ensure the enduring defeat of Daesh and other terrorist organizations,” spokesperson Anouar El Anouni said.

Greece’s Prime Minister Kyriakos Mitsotakis expressed anger after the attack on the Greek Orthodox Church, calling on the new authorities “to take concrete measures to protect all ethnic and religious minorities.”

Syria’s Christian community has shrunk from around one million before the war to fewer than 300,000 due to waves of displacement and emigration.

Daesh seized large swathes of Syrian and Iraqi territory in the early years of the civil war, declaring a cross-border “caliphate” in 2014.

The militants were territorially defeated in Syria 2019 but have maintained a presence, particularly in the country’s vast desert.
