CAIRO/JERUSALEM, Aug 1 (Reuters) - President Donald Trump's Middle East envoy became the first high-profile U.S. official to visit Gaza since the war began, touring a U.S.-backed aid operation on Friday that the United Nations says is partly to blame for deadly conditions in the enclave.

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.

U.S. Ambassador to Israel Mike Huckabee also visited Gaza "to learn the truth about" Gaza Humanitarian Foundation sites.
