Amid escalating tensions in the Middle East following Iran’s weekend missile and drone attack, Israel’s European allies have called for restraint, urging Israeli leaders to step back from the brink of further escalation.

Israeli Prime Minister Benjamin Netanyahu’s war cabinet, responsible for determining the country’s response, convened on Monday afternoon following the attack. While Israeli officials favored retaliation, the cabinet remained divided over the timing and scale of any potential response.

With the risk of open warfare looming between Israel and Iran, and tensions already high over the conflict in Gaza, President Joe Biden conveyed to Netanyahu that the United States would not participate in any Israeli counter-offensive against Iran, according to U.S. officials.

Britain, France, Germany, and the European Union’s foreign policy chief, along with Washington and United Nations Secretary-General Antonio Guterres, have all echoed calls for restraint. “We’re on the edge of the cliff and we have to move away from it,” said Josep Borrell, the EU’s High Representative for Foreign Affairs and Security Policy.

French President Emmanuel Macron urged Israel to focus on isolating Iran rather than escalating the situation, while German Chancellor Olaf Scholz warned Iran against further attacks and stressed Israel’s role in de-escalation.

Despite being Iran’s ally, Russia expressed concern about the risk of escalation on Monday and also appealed for restraint. “Further escalation is in no one’s interests,” said Kremlin spokesman Dmitry Peskov.

The missile and drone attack, reportedly launched by Iran, followed a suspected Israeli airstrike on its embassy compound in Syria on April 1, which resulted in the death of seven Iranian Revolutionary Guards officers, including two senior commanders. The incident escalated tensions that had been simmering for months due to clashes between Israel and Iran’s regional allies, triggered by the Gaza war that spilled over into other fronts across the region.

Despite the significant scale of the attack, which involved more than 300 missiles and drones, Israel’s Iron Dome defense system, aided by the U.S., Britain, France, and Jordan, managed to intercept most of the projectiles. The attack caused only modest damage in Israel, with the only reported serious injury being a seven-year-old child hurt by shrapnel.
