The Israeli army said on Monday it was resuming its strikes on the Gaza Strip, after the end of a seven-hour humanitarian lull.

"We are resuming our operations, including air strikes, against terrorist infrastructures in Gaza," spokesman Lieutenant Colonel Peter Lerner told AFP.

He said troops were redeploying within Gaza while other forces were pulling out in a process which began on Saturday.

According to Gaza officials, 1,820 Palestinians have been killed and more than a quarter of its 1.8 million residents have been displaced so far. Israel has confirmed that 64 soldiers have died in combat, while Palestinian shelling has killed three civilians in Israel.
