NOUR SHAMS REFUGEE CAMP, West Bank: Israeli airstrikes struck militant sites in Gaza on Sunday for the third straight day, the Israeli military said, after Palestinian militants near the border fence launched incendiary balloons into Israel and threw an explosive at soldiers. The strike came on the heels of an Israeli military raid in the northern West Bank that Palestinian health officials said killed two Palestinians.

It was the latest bloodshed in a surge of violence during a sensitive Jewish holiday period. A series of violent escalations on the border between Israel and Gaza over the past week has raised the specter of an escalation for the first time since a brief round of conflict last May between Israel and the Palestinian Islamic Jihad militant group.
