Hezbollah formally entered the U.S.-Israeli war against Iran this week, launching over 150 rockets and drones at northern Israel in what the group called a coordinated operation with Tehran. Israel responded with 'large-scale' strikes across Lebanon, including Beirut. These facts are confirmed by Fox News, CNN, NPR, Al Jazeera, and the Times of Israel.

The escalation marks a significant widening of the conflict. UNIFIL, the UN peacekeeping force in Lebanon, reported monitoring over 210 missiles fired by Hezbollah into Israel since March 2. Fox News reported Hezbollah declared readiness for 'open war,' while a senior researcher at the Institute for National Security Studies told Fox that 'Hezbollah has fully joined the war, and it looks like they are now very well coordinated with Iran.'

Israel's counterstrikes killed at least 31 people in a Beirut strike following the rocket attacks, per Al Jazeera. Overall, Israeli airstrikes have killed nearly 500 people in Lebanon, including 83 children, and displaced approximately 500,000 people. Israel issued evacuation warnings for all of southern Lebanon, ordering residents north of the Litani River.

Israeli ground forces entered several southern Lebanese towns including Kfar Kila, Houla, and Khiam. Lebanese Prime Minister Nawaf Salam declared all Hezbollah military activities illegal and ordered the group to disarm — an extraordinary step confirmed by NPR and CNN.

Iran's IRGC navy separately fired on and stopped two vessels in the Strait of Hormuz, further escalating the maritime dimension of the conflict.
