One in three people are going without food for days, the U.N. said, as global outrage grows over Israel’s restrictions on aid to Gaza.

The German government observes a "initial slight progress in humanitarian aid for the population in the Gaza Strip," according to spokesman Stefan Kornelius on Saturday, though he noted it remains insufficient to alleviate the emergency.

Famine is "playing out" in the Gaza Strip, a global hunger monitor said in an alert issued on Tuesday as international criticism of Israel intensifies over rapidly worsening conditions in the Palestinian enclave.
