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.

Khan Younis: At least 45 Palestinians were killed in the Gaza Strip while waiting for UN and commercial trucks to enter the territory with desperately needed food, according to Gaza's Health Ministry and a local hospital. The circumstances of the killings were not immediately clear.

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.
