Despite a cease-fire between Hezbollah and Israel, the IDF targeted Beirut, Lebanon, with airstrikes Sunday while also killing at least dozens of Palestinians with strikes in Gaza as the war continues.

Israeli jets struck Beirut’s southern suburbs Sunday after issuing a warning about an hour earlier, marking the third Israeli strike on the area since a ceasefire took effect in late November. A huge plume of smoke billowed over the area after the strike.

The attack raised concerns that the cease-fire that ended a war between Israel and Lebanese militants might be in jeopardy.
