Joe Biden reportedly warned Benjamin Netanyahu that the US will not participate in any Israeli counter-attacks against Iran.

The US president and his senior advisers are highly concerned that an Israeli response to Iran’s attack would lead to a regional war with catastrophic consequences, US officials told Axios.

On Saturday evening, Iran launched its first-ever direct attack on Israel, involving more than 300 drones and missiles. The attack came in retaliation to an airstrike in Syria on April 1 that killed seven of Iran’s Islamic Revolutionary Guard Corps – Israel has neither confirmed nor denied responsibility.

Mr Biden said the US and Israel had shot down “nearly all” of the drones and missiles launched by Tehran overnight, aided also by Britain, France and Jordan. Israel said 99 per cent were intercepted without hitting their targets and that “very little damage” had been caused.

American forces intercepted 70 drones and at least three ballistic missiles, according to CNN, while Mr Biden also said that US support for Israel was “ironclad”.

“You got a win. Take the win,” Mr Biden reportedly told Mr Netanyahu, adding that the US will not participate in any offensive operations. Mr Netanyahu reportedly said that he understands the US’s position.

Iran has said the attacks “achieved all its objectives” and that it is not planning any further operations. It warned Israel against taking any “reckless” actions, and said it would not hesitate to retaliate with a “much stronger response”.

However, Israel has said the “campaign is not over yet”.

Lloyd Austin, the US secretary of defence, has asked that Israel notify the US ahead of any response against Iran.

World leaders have condemned Iran’s attack, with regional powers Saudi Arabia and Egypt calling for restraint. Leaders from the G7 will hold a video conference later on Sunday to discuss the Iranian strikes and coordinate a united diplomatic response. By Harriet Barber, Telegraph
