New Israeli bombardment comes on the verge of a U.S. deadline for Israel to ramp up humanitarian aid allowed into Gaza or risk restrictions on military aid.

Palestinian medical officials say two Israeli strikes in Gaza killed at least 14 people, including two children and a woman, most in an Israeli-declared humanitarian zone.

Israeli attacks have created deplorable conditions across Gaza, but humanitarian groups say the month-long siege of towns in the north have essentially rendered the area unlivable.And they accuse Israel's military of inflicting starvation and destruction to ensure hundreds of thousands of Palestinians can never return to their homes.
