Israel launched hundreds of airstrikes in southern and eastern Lebanon on Monday, killing more than 270 people, as the Israeli military called on residents to immediately evacuate places where it claimed the Hezbollah militant group stores weapons.

Israel’s air force has carried out dozens of airstrikes on southern Lebanon as the Israeli military called on people in the area to immediately evacuate homes and other buildings where it claims the Hezbollah militant group stores weapons.

Thousands of Lebanese fled the south, and the main highway out of the southern port city of Sidon was jammed with cars heading toward Beirut in the biggest exodus since the 2006 conflict.
