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.

Palestinian witnesses told The Associated Press that Israeli forces carried out an airstrike on a nearby home before opening fire toward the crowd in the southern city of Khan Younis.

An airstrike killed seven other people in Beit Lahiya town north of the enclave, medics said. In Nuseirat camp in central Gaza Strip, medics said an Israeli airstrike killed at least 11 people in a house. The rest were killed in separate airstrikes in the southern Gaza Strip, they added.
