Lebanon is marking a national day of mourning following Sunday’s Israeli air strike in the town of Qana that killed about 57 civilians, mostly children. Israel has announced it will temporarily halt air strikes in southern Lebanon but its ground troops continue to fight in the south. The Lebanese government says the killings in Qana bring the death toll in Lebanon to about 750 since the war began 20 days ago. Israeli warplanes bombed the village of Qana at around 1 a.m. on Sunday. A missile hit a three-story building where relatives from two extended families were seeking refuge. As many as 57 died including 37 children. There were only eight survivors. The youngest of the dead was 10 months old. The oldest was 95. One person was in a wheelchair. Survivors said the family didn’t have enough money to evacuate to a safer area. Rescue workers were unable to reach the site for hours because Israeli warplanes continued to attack the area. No weapons were found in the building that was hit.
