U.S. President Donald Trump's Mideast envoy on Friday visited a food distribution site in the Gaza Strip operated by an Israeli-backed American contractor whose efforts to deliver food to the hunger-stricken territory have been marred by violence and controversy.

As global concern over the crisis in Gaza intensifies, Steve Witkoff, Trump's special envoy to the Middle East, visited an aid distribution site in the enclave.

Hospitals in Gaza reported the killing of more than a dozen people, eight of them food-seekers, by Israeli fire on Saturday as Palestinians endured severe risks in their search for food amid airdrops and restrictions on overland aid delivery.
