Israelis awaited word on how Prime Minister Benjamin Netanyahu would respond to Iran’s first-ever direct attack as international pressure for restraint grew amid fears of an escalation of the conflict in the Middle East, Reuters reports.

Netanyahu on Monday summoned his war cabinet for the second time in less than 24 hours to weigh a response to Iran’s weekend missile and drone attack, a government source said.

Military Chief of Staff Herzi Halevi said Israel would respond. He provided no details.

“This launch of so many missiles, cruise missiles, and drones into Israeli territory will be met with a response,” he said at the Nevatim Airbase in southern Israel, which sustained some damage in Saturday night’s attack.

Iran launched the attack in retaliation for what it says was an April 1 Israeli airstrike on its embassy compound in Damascus, and signalled that it does not seek further escalation.
