Israel’s air force carried out dozens of airstrikes early Monday on southern Lebanon, state media and the Israeli military said.

The Israel Defense Forces announced Sunday morning it was conducting strikes against the terror group Hezbollah in Lebanon after the group had attacked northern Israel.

Lebanon’s Hezbollah has launched over 100 rockets into northern Israel in response to ramped-up Israeli attacks that killed dozens of people in Beirut, including a veteran leader of the militant group.
