US and European diplomats went on a flurry of calls in the hours after US President Donald Trump offered on Monday to join prospective Ukraine-Russia talks later this week, trying to find a path that would bring an end to the war in Ukraine.
Trump’s surprise offer to join the talks on Thursday in Istanbul came a day after Ukrainian President Volodymyr Zelensky, in a fresh twist to the stop-start peace talks process, said he would travel to Turkiye and wait to meet President Vladimir Putin there.
After Trump’s announcement, US Secretary of State Marco Rubio discussed the “way forward for a ceasefire” in Ukraine with European counterparts, including the foreign ministers of Britain and France, and the EU’s foreign policy chief, the State Department said on Monday.
Ukraine’s Foreign Minister Andrii Sybiha and his German and Polish counterparts were also on the call, according to the readout.
Russian Foreign Minister Sergei Lavrov held talks late on Monday with his Turkish counterpart Hakan Fidan to discuss Moscow’s direct talks with Kyiv — a proposal that came from Putin at the weekend, the Russian foreign ministry said.
It remained unclear who would travel from Moscow to Istanbul to take part in the direct talks, which would be the first between the two sides since the early days of the war that Russia launched with its invasion on Ukraine in February 2022.
There has been no response from the Kremlin to Zelensky’s offer to meet Putin in Istanbul and Moscow was yet to comment on Trump’s offer to join the talks.
If Zelensky and Putin, who make no secret of their contempt for each other, were to meet on Thursday it would be their first face-to-face meeting since December 2019.
“Don’t underestimate Thursday in Turkiye,” Trump told reporters at the White House on Monday.
Trump’s current schedule has him visiting Saudi Arabia, the United Arab Emirates and Qatar this week.
Ukraine and its European allies have been seeking to put pressure on Moscow to accept an unconditional 30-day ceasefire from Monday, with the leaders of four major European powers traveling to Kyiv on Saturday to show unity with Zelensky.
Earlier on Monday, the German government said Europe would start preparing new sanctions against Russia unless the Kremlin by the end of the day started abiding by the ceasefire.
Ukraine’s military said on Monday that fighting along parts of the frontline in the country’s east was at the same intensity it would be if there were no ceasefire.
Putin called the Western European and Ukrainian demands for a ceasefire “ultimatums” that the Kremlin said on Monday are for Russia an unacceptable language.
Konstantin Kosachev, chairman of the international affairs committee of the Federation Council, the upper house of Russia’s parliament, told the Izvestia media outlet in remarks published on Tuesday that the talks between Moscow and Kyiv can move further than they did in the 2022.
“If the Ukrainian delegation shows up at these talks with a mandate to abandon any ultimatums and look for common ground, I am sure that we could move forward even further than we did,” Izvestia cited Kosachev as saying.

LONDON: Rights groups and NGOs are dragging the UK government to court on Tuesday accusing it of breaching international law by supplying fighter jet parts to Israel amid the war in Gaza.
Supported by Amnesty, Human Rights Watch, Oxfam and others, the Palestinian rights association Al-Haq is seeking to stop the government’s export of UK-made components for Lockheed Martin F-35 fighter jets.
Israel has used the American warplanes to devastating effect in Gaza and the West Bank, and the head of Amnesty UK said Britain had failed to uphold its “legal obligation... to prevent genocide” by allowing the export of key parts to Israel.
The plane’s refueling probe, laser targeting system, tires, rear fuselage, fan propulsion system and ejector seat are all made in Britain, according to Oxfam, and lawyers supporting Al-Haq’s case said the aircraft “could not keep flying without continuous supply of UK-made components.”
It is not clear when a decision could be made following the four-day hearing at London’s High Court, the latest stage in a long-running legal battle.
Lawyers for the Global Action Legal Network  have said they launched the case soon after Israel’s assault on Gaza was triggered by the October 7, 2023 Hamas-led attacks.
Israel has repeatedly denied accusations of genocide.
The lawyers said the UK government had decided in December 2023 and April and May 2024 to continue arms sales to Israel, before in September 2024 then suspending licenses for weapons which were assessed as being for military use by the Israeli army in Gaza.
The new Labour government suspended around 30 licenses following a review of Israel’s compliance with international humanitarian law, but the partial ban did not cover British-made parts for the advanced F-35 stealth fighter jets.
A UK government spokesperson told AFP it was “not currently possible to suspend licensing of F-35 components for use by Israel without prejudicing the entire global F-35 program, due to its strategic role in NATO and wider implications for international peace and security.”
“Within a couple of months of coming to office, we suspended relevant licenses for the IDF that might be used to commit or facilitate serious violations of International Humanitarian Law in Gaza,” they said.
The government insisted it had “acted in a manner consistent with our legal obligations” and was “committed to upholding our responsibilities under domestic and international law.”
But GLAN described the F-35 exemption as a “loophole” which allowed the components to reach Israel indirectly through a global pooling system.
Charlotte Andrews-Briscoe, a lawyer for GLAN, told a briefing last week the UK government had “expressly departed from its own domestic law in order to keep arming Israel,” with F-35s being used to drop “multi-ton bombs on the people of Gaza.”
Hamas’s 2023 attack on southern Israel resulted in the deaths of 1,218 people, mostly civilians, according to an AFP tally based on official figures.
The health ministry in Hamas-run Gaza said on Monday that at least 2,749 people have been killed since Israel ended a two-month ceasefire in mid-March, bringing the overall death toll since the war broke out to 52,862.
“Under the Genocide Convention, the UK has a clear legal obligation to do everything within its power to prevent genocide,” said Sacha Deshmukh, Amnesty International UK’s chief executive.
“Yet the UK government continues to authorize the export of military equipment to Israel — despite all the evidence that genocide is being committed by Israel against the Palestinian people in Gaza. This is a fundamental failure by the UK to fulfil its obligations.”
Al-Haq’s general director Shawan Jabarin said: “The United Kingdom is not a bystander. It’s complicit, and that complicity must be confronted, exposed and brought to account.”
