Following a brief lull, rocket fire from Gaza resumed and an Israeli airstrike reportedly killed ten people near the entrance to a United Nations school on Sunday.

The biggest news was word of an Israeli airstrike in southern Gaza that reportedly killed ten people and wounded scores of others: 

Witnesses said those killed or hurt were waiting in line for food supplies when a missile hit. A photographer said the target appeared to be a motorcycle near the entrance of the school in the center of Rafah. About 3,000 Palestinians in the area, where the Israeli military has been battling Hamas and Islamic Jihad fighters, had been sheltering in the school.

The Israeli military had no immediate comment, and the United Nations said it was not immediately clear where the strike originated.

The United Nations has since revised that comment as Secretary-General Ban Ki-moon called it a "moral outrage and a criminal act" as well as a "gross violation of international humanitarian law," but stopped short of placing specific blame for the event. 

According to the Gaza Health Ministry, which is run by Hamas, Sunday's fighting put the Palestinian death toll past 1800 since the conflict began nearly a month ago. On Saturday, Israel's deputy foreign minister estimated 47 percent of those killed in Gaza were combatants. Palestinian officials say that at least 80 percent of the dead in Gaza are civilians.

Israel removed many of its ground troops from Gaza on Saturday as the military says it is nearly finished demolishing tunnels used by Hamas and other groups in the Gaza Strip. Sunday's airstrike took place in Rafah, deep in southern Gaza, where three Israeli soldiers were attacked and killed in the opening hours of what was supposed to be a 72-hour ceasefire. (Hamas maintains the attack took place prior to the ceasefire.)

One of the soldiers, Hadar Goldin, was initially thought to have been abducted alive by Hamas, but was later declared dead. Goldin's body remains missing, but a funeral was held on Sunday at which his father, twin brother, and fiancee reportedly spoke.
