Sky News, citing a statement from the Israeli immigration ministry, says that the detained parliamentarians are Labour MPs Yuan Yang and Abtisam Mohamed, who were rejected because they were suspected of plans to “document the activities of security forces and spread anti-Israel hatred.”

Yang represents the Earley and Woodley constituency, while Mohamed is the MP for Sheffield Central. Both had flown to Israel from Luton on Saturday, Sky News said.

“I have made clear to my counterparts in the Israeli government that this is no way to treat British Parliamentarians, and we have been in contact with both MPs tonight to offer our support,” Lammy said.

“The UK government’s focus remains securing a return to the ceasefire and negotiations to stop the bloodshed, free the hostages and end the conflict in Gaza,” he further added.
