BEIRUT >> Palestinians in northern Gaza described heavy Israeli bombardment Saturday in the hours after airstrikes killed at least 22 people, as Israel warned people there and in southern Lebanon to get out of the way of offensives against the Hamas and Hezbollah militant groups.

In Lebanon, the U.N. peacekeeping force said that its headquarters in Naqoura was hit again, with a peacekeeper struck by gunfire late Friday and in stable condition. It wasn’t clear who fired. The shooting occurred a day after Israel’s military fired on the headquarters for a second straight day. Israel, which has warned peacekeepers to leave their positions, didn’t immediately respond to questions.

Hunger warnings emerged again in northern Gaza as residents said they hadn’t received aid since the beginning of the month. The U.N. World Food Program said that no food aid had entered the north since Oct. 1. An estimated 400,000 people remain there.
