The U.N. Security Council unanimously adopted Resolution 1701 in August 2006 as part of a cease-fire that ended Israel’s last war with Lebanon. The resolution sought to create a buffer zone in southern Lebanon to prevent fighting between Israel and Hezbollah, but has failed to keep the peace.

Saturday’s attack completely demolished a multistory building in a densely populated neighborhood. Israel did not say who the strike’s target was.

Footage showed the strikes hit the multi-storey building, which topped in a cloud of smoke as civilians watched the high rise turn to dust.
