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.

The UN says at least 1,373 Palestinians have been killed near aid sites since late May - Israel says its forces do not intentionally shoot civilians.

Israel’s nearly 22-month military offensive against Hamas has shattered security in the territory of some 2 million Palestinians and made it nearly impossible to safely deliver food to starving people.
