Israel has said it expects the UK to join it in attacking “significant” targets in Iran in response to any strikes by Tehran.
The comments came as David Lammy, the Foreign Secretary, visited Jerusalem on Friday to meet his French and Israeli counterparts.
Israel Katz told Mr Lammy and Stephane Sejourne that if Iran attacked Israel “we expect the coalition to join Israel not only in defence but also in striking significant targets in Iran.”
Israel will not be able to refrain from responding “forcefully to any harm against it,” Mr Katz said. He added that if Iran did not stop its “aggression” it would “pay a price soon”.
Mr Lammy called it “a dangerous moment for the Middle East” and warned that the risk of the situation spiralling out of control was “rising.”
“Any Iranian attack would have devastating consequences for the region,” he added.
The Foreign Secretary also called on Hamas and Israel to engage “seriously” in ceasefire negotiations, which continued on Friday in Doha, Qatar.
“There can be no delays or excuses… This is a vital opportunity to secure the release of hostages and an immediate surge in aid into Gaza,” he said.
