Gaza's health ministry says at least 60 people were killed by Israeli strikes in a 24-hour period as Israel let in minimal aid to the strip and many Gazans face a high risk of famine.

United Nations chief Antonio Guterres on Friday said Israel has only authorized for Gaza what "amounts to a teaspoon of aid when a flood of assistance is required" and again signaled that the U.N. won't take part in a new U.

Israel allowed 100 aid trucks into the Gaza Strip, the Israeli military said, as UN officials reported that no aid had so far reached people in need.
