A cease-fire between Israel and Iran-backed group Hezbollah came into effect on Wednesday after U.S. President Joe Biden said both sides accepted an agreement brokered by the United States and France.

Bursts of gunfire could be heard across Beirut after the cease-fire took effect. It was not immediately clear if the shooting was celebratory, as gunfire had also been used to alert residents who may have missed evacuation warnings issued by Israel’s military.

Streams of cars began heading to southern Lebanon, which borders Israel, after the cease-fire early on Wednesday, according to Reuters witnesses.
