At least 51 people were killed and more than 200 others injured by Israeli fire as they waited for aid trucks to arrive in Khan Younis in southern Gaza early Tuesday morning, the Palestinian Ministry of Health said.

At least eight people seeking aid have been shot to death by Israeli troops in Rafah, making 118 total since late May.

Israeli fire killed at least 50 people on Monday, nearly half of them near an aid distribution site run by the U.S.-backed Gaza Humanitarian Foundation, the territory's Health Ministry said, as U.N. officials denounced Israeli-backed aid delivery methods.
