The aerial campaign is an escalation from a year of cross-border warfare between Israel and the Lebanese group since the start of its offensive on the Gaza Strip, in which Israel has killed more than 42,600 people, most of them women and children, since a cross-border attack by the Palestinian group Hamas last October.

The airstrike in the Bachoura neighborhood was the deadliest so far in the Lebanese capital. The area is close to government and U.N. buildings.
