Rishi Sunak has confirmed that the RAF shot down "a number" of Iranian attack drones in defence of Israel on Saturday night.
The Prime Minister confirmed that the UK sent "additional planes" to the region as part of missions already under way against Isis in Syria and Iraq.
The jets were given permission to shoot down any Iranian missiles or drones as part of the missions, meaning where they were operating near Syrian and Iraqi airspace, rather than over Israel.
Sunak said the UK participated in an “international coordinated effort” to intercept the missiles and drones fired.
