British judges will rule today on a legal challenge brought by a Palestinian human rights organisation seeking to block the UK from supplying components for Israeli F-35 fighter jets, AFP reports.

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.

Previously, the UK government had suspended some export licences 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 defence programme that produces and maintains the F-35s.

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.

The London court is due to give its ruling at 9:30am GMT (2:30pm PKT).
