At least 72 people have been killed and 437 injured in Israeli airstrikes across Lebanon, according to the Lebanese Ministry of Health. The attacks began early Monday and have displaced 83,847 people who are now taking shelter in government facilities, the country’s social welfare minister said.

The strikes follow rocket attacks launched by Iran-backed Hezbollah into northern Israel, which the group said were in retaliation for U.S. and Israeli strikes in Tehran after the death of Iran’s Supreme Leader Ayatollah Ali Khamenei. In response, Israel has intensified its military operations, launching extensive air raids and initiating new ground incursions into Lebanese territory.

Israeli forces have reportedly ordered residents to evacuate southern Lebanon and the southern suburbs of Beirut, signaling a potential expansion of the conflict within Lebanon’s borders.
