Tensions between Iran and Israel remain high as Iran's military heads vow a 'crushing' response to Israeli strikes, while the UN's atomic watchdog warns against attacking Iran's nuclear sites. Director General of the International Atomic Energy Agency Rafael Grossi issued a warning to Israel, stating that Iran's nuclear installations should not be attacked. The White House has repeatedly warned Israel against targeting Iran's nuclear sites. Iran appears undeterred by threats and promises a retaliatory blow following Israel's attacks in October. Israel has ramped up its attacks against Iran-backed proxies like Hezbollah in Lebanon and the Islamic Jihad terrorist organization in Syria.
