LONDON: British judges will rule on Monday on a legal challenge brought by a Palestinian human rights organization seeking to block the UK from supplying components for Israeli F-35 fighter jets.

Israel has used the jets to devastating effect in its bombardment of Gaza, with both sides being accused of atrocities during a conflict that has killed tens of thousands — mostly Palestinian civilians, according to the Hamas-run territory’s health ministry.

The UK government suspended some export licenses for military equipment after concluding there was a risk Israel could be breaching international humanitarian law, but made an exemption for some parts for Lockheed Martin F-35 stealth jets.

In its claim to the High Court, rights group Al-Haq said the “carve out” was unlawful, alleging the government had misunderstood the applicable rules of international law — a claim denied by ministers.

The UK contributes components to an international defense program that produces and maintains the F-35s.

Defense Secretary John Healey said a suspension would impact the “whole F-35 program” and have a “profound impact on international peace and security.”

The London court is due to give its ruling at 0930 GMT.

Al-Haq, which is supported by Amnesty International, Human Rights Watch, Oxfam and others in its case, is seeking a court order to stop the supply of UK-made parts for the US warplanes.

Lawyers for Al-Haq said the government had known there was a “clear risk” Israel would use the jet parts to commit violations of international law.

But government lawyer James Eadie said the UK’s trade department had acted lawfully.

He added the court was not placed to rule on the legality of Israel’s actions, and that attempting to do so could have a “potentially deleterious” effect on “foreign relations with a friendly state, namely Israel.”

In September 2024, the new Labour government announced it was suspending around 30 of 350 export licenses following a review of Israel’s compliance with international humanitarian law.

But the partial ban did not cover British-made F-35 parts, which include refueling probes, laser targeting systems, tires and ejector seats, according to Oxfam.

Healey has previously said suspending F-35 licenses would “undermine US confidence in the UK and NATO” but lawyers for Al-Haq have described the exemption as a “loophole.”

UK-based NGO Campaign Against Arms Trade has said that licensing figures showed the government had made a “shocking increase in military exports to Israel” in the months after its September 2024 announcement of partial suspensions.

It said the figures showed the UK approved £127.6 million ($170 million) in military equipment to Israel in single-issue licenses from October to December 2024, saying this was more than for the period from 2020 to 2023 combined.

Most of the licenses were for military radars, components and software, as well as targeting equipment, according to the NGO, which was involved in the case against the government.

KYIV: German Foreign Minister Johann Wadephul made an unannounced visit to Kyiv on Monday, in a show of continuing support for Ukraine’s fight to repel Russia’s invasion as US-led international peace efforts fail to make progress.

Wadephul was due to meet with Ukraine President Volodymyr Zelensky and Ukrainian Foreign Minister Andrii Sybiha.

Wadephul said in a statement that Germany will help Ukraine “continue to defend itself successfully — with modern air defense and other weapons, with humanitarian and economic aid.”

Germany has been Ukraine’s second-largest military backer after the United States, whose continuing support is in doubt.

However, Berlin has balked at granting Zelensky’s request to provide Ukraine with powerful German- and Swedish-made Taurus long-range missiles. That’s due to fears that such a move could enrage the Kremlin and end up drawing NATO into Europe’s biggest conflict since World War II.

Instead, German Chancellor Friedrich Merz pledged in May to help Ukraine develop its own long-range missile systems that would be free of any Western-imposed limitations on their use and targets.

Wadephul was accompanied on his trip to Kyiv by German defense industry representatives.

Russia’s invasion shows no sign of letting up. Its grinding war of attrition along the roughly 1,000-kilometer (620-mile) front line and long-range strikes on civilian areas of Ukraine have killed thousands of troops and civilians.

The Russian effort to capture more Ukrainian territory has been costly in terms of casualties and damaged armor. But Russian President Vladimir Putin has effectively rejected a ceasefire and hasn’t budged from his war goals.

Putin “doesn’t want negotiations, but (Ukrainian) capitulation,” Wadephul said in his statement.

Russia launched its biggest combined aerial attack against Ukraine at the weekend, Ukrainian officials said, in its escalating bombing campaign that has further dashed hopes for a breakthrough in peace efforts.
