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.

Dozens of people were killed in Israeli military strikes on northern Lebanon and the Gaza strip, including as many as 20 children, authorities said.

The Israel Defense Forces continued its intense airstrike and ground campaigns in Gaza -- particularly in the north of the strip -- and in Lebanon, with Israeli attacks on targets nationwide including in the capital Beirut.
