An anti-missile system operates after Iran launched drones and missiles toward Israel on April 14.

Iran launched hundreds of drones and missiles at Israel on Saturday, sparking President Joe Biden to call for a meeting of the G7 nations “to coordinate a united diplomatic response” to the “brazen attack.”

Biden said the U.S. and other allies helped Israel to intercept most of the projectiles. As of Sunday morning, it wasn’t clear how much damage was caused by the attacks.

The U.S. and Israel had anticipated Saturday’s strike, which came in retaliation for the April 1 bombing of Iran’s embassy in Syria. Iran said it now considers that matter “concluded,” but also warned Israel and the US against any retaliation. 

Biden told Israel Prime Minister Benjamin Netanyahu that since the attacks appeared to have caused minimal casualties and damage, the U.S. will not help in any counter-attacks against Iran, a senior administration official told NBC News.

However, officials are reportedly worried Israel will retaliate anyway.

NATO calls Iran attack an ‘escalation’

The North Atlantic Treaty Organization, or NATO, has condemned Iran’s attack on Israel, and called for Israel to pause on any possible retaliation attempts.

“We condemn Iran’s overnight escalation, call for restraint, and are monitoring developments closely,” NATO spokesperson Farah Dakhlallah, wrote on X. “It is vital that the conflict in the Middle East does not spiral out of control.”

Which countries were involved in the strikes?

According to BBC News, projectiles were fired toward Israel from Iran, Iraq, Syria and Yemen.

Over 99% of the drones and missiles were intercepted with the help of the United States, the United Kingdom, France and Jordan. 

Saudi Arabia might have played an indirect role in the interception as well, according to the British publication the Economist, since the country has “Western air-defense systems, surveillance and refueling aircraft that would have been vital for the effort.”

U.K. Prime Minister Rishi Sunak confirmed that the Royal Air Force struck down “a number of Iranian attack drones” when speaking to journalists in Downing Street on Sunday.

Those efforts, said Sunak, saved lives in Israel and in neighboring countries like Jordan.

“I can confirm that our planes did shoot down a number of Iranian attack drones,” he said. “I want to pay tribute to the bravery and professionalism of our pilots flying into the face of danger to protect civilians.”

Added Sunak: “If this attack had been successful, the fallout for regional stability would be hard to overstate, and we stand by the security of Israel and the wider region, which is of course important for our security here at home.”

Biden and his national security team met on Saturday night, joining forces with other nations to stop Iran’s attack on Israel.

Biden cut a weekend at his Delaware beach house short amid news of the attack. The White House said Biden convened a meeting of the National Security Council in the White House Situation Room.
