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.

An Israeli strike on a home in northern Gaza killed three siblings aged 6 and under, among at least six people killed in airstrikes in the war-ravaged territory, Palestinian medics said. In Lebanon, an Israeli airstrike on an apartment building south of Beirut on Wednesday killed at least six people and wounded 15, the Health Ministry said.

An Israeli airstrike killed at least 23 people in the village of Aalmat, north of Beirut and far from the areas in southern and eastern Lebanon where the militant Hezbollah group has a major presence. Lebanon's Health Ministry said a further six people were wounded. There was no immediate Israeli comment.
