Israel and Iran launched fresh attacks on each other overnight into today. Prime minister Benjamin Netanyahu said the attacks by Israel so far were nothing compared with what Iran would see in the coming days.

Speaking to Sky News, Reeves called for a de-escalation in the conflict and said the decision to send additional jets to the region was a “precautionary move”.

Asked if Britain would come to Israel’s aid if asked, Reeves said: “We have, in the past, supported Israel when there have been missiles coming in.”

“We’re sending in assets to both protect ourselves and also potentially to support our allies,” she added.

Britain was involved last year in protecting Israel from missile attacks from Iran.

In April, British planes shot down Iranian drones heading for Israel and in October it said two of its fighter jets and an air-to-air refuelling tanker were involved in trying to intercept Iranian missiles. The jets did not engage any targets.
