Israel and Iran traded threats on Tuesday after Tehran’s first ever direct attack on its arch foe sharply heightened regional tensions as the Gaza war ground on with no truce in sight. Israeli military spokesman Rear Admiral Daniel Hagari said Iran would not get off “scot-free” after Iran and its allies launched a barrage of over 300 missiles, drones and rockets at Israel at the weekend. “We cannot stand still from this kind of aggression,” Hagari said, a day after Israel’s military chief vowed there would “a response” to Iran’s offensive. Iran said its attack was an act of self-defence following a deadly Israeli air strike on its consulate in Syria, and that it would consider the matter “concluded” unless Israel retaliated. Iran’s President Ebrahim Raisi warned that “the slightest action against Iran’s interests will definitely be met with a severe, extensive and painful response”. US President Joe Biden stressed on Monday that “the United States is committed to Israel’s security” and wants to prevent the conflict from spreading. Washington, Israel’s top ally and arms supplier, has made clear it will not join Israel in any attack on their common adversary Iran, a senior US official said. World leaders have urged restraint and de-escalation. During a phone call with Iran’s Raisi, Russian President Vladimir Putin called on both sides to “prevent a new round of confrontation fraught with catastrophic consequences for the entire region”, the Kremlin said. Israel has meanwhile kept bombing targets in Gaza, the Hamas-ruled coastal territory that has been largely devastated by more than six months of war and a siege on its 2.4 million people. – Israel weighs options – Since the Iranian attack, Israeli Prime Minister Benjamin Netanyahu has twice convened his war cabinet, set up after Palestinian militant group Hamas launched the October 7 attack that sparked the bloodiest ever Gaza war. Israel was weighing its options after the Iranian drone and missile onslaught, which caused little damage as Israeli defences intercepted most projectiles, helped by US, British and French forces as well as regional allies. It remained unclear when Israel might strike and whether it would target Iran directly or attack its interests or allies abroad, including in Lebanon, Syria, Iraq and Yemen. Iran-backed armed groups across the region have carried out attacks since the Israel-Hamas war broke out. Hezbollah, which has been trading regular cross-border fire with Israel, claimed an attack with two explosive drones near a northern Israeli town on Tuesday, which the local council said wounded three people. Also on Tuesday, an Israeli strike killed a local Hezbollah commander in southern Lebanon, a source close the group and the Israeli military said.
