Israeli troops opened fire on Saturday toward crowds of Palestinians seeking food from distribution hubs run by a US and Israeli-backed group in southern Gaza in Rafah, killing at least 36 people, according to witnesses and hospital officials. The two incidents occurred near hubs operated by the Gaza Humanitarian Foundation.

Troops fired warning shots before opening fire at the marching people. Mahmoud Mokeimar, an eyewitness, said, “It was a massacre. The occupation opened fire at us indiscriminately.”

While the GHF says it has distributed millions of meals to hungry Palestinians, local health officials and witnesses say that hundreds of people have been killed by Israeli army fire as they try to reach the distribution hubs. The army and GHF did not immediately comment on Saturday’s violence.
