Israel-Iran Escalation: Israel and Iran traded fresh airstrikes Monday, with Israel saying it hit strategic air defense systems and military targets in western and central Iran after Iranian missile waves; Iran’s IRGC claimed it struck Israeli bases including Nevatim and Tel Nof and framed the exchange as “Operation Nasr,” while explosions were reported across Tehran and other cities. Ceasefire Under Strain: The tit-for-tat came despite US President Trump urging Netanyahu not to retaliate after Iran’s initial attack tied to a Beirut strike, raising fears the April ceasefire is unraveling. Lebanon Fallout: Israel hit southern Beirut suburbs days after a US-backed ceasefire push, and Egypt condemned Israel’s attack on a Lebanese army patrol, warning of dangerous escalation. Home Front Measures: Israel’s Home Front Command tightened security, moving to restricted activity, shutting schools and canceling exams nationwide for the day amid missile alerts. Red Sea Disruption: Yemen’s Houthis announced a complete ban on Israeli-linked Red Sea navigation and warned they would treat Israeli-affiliated vessels as military targets, adding another front to the regional crisis. Espionage Case: Israel Police and Shin Bet arrested a Bat Yam man accused of contacting Iranian intelligence via social media and carrying out security-related missions.
