At least 37 Palestinians were killed on Monday in new shootings in Gaza near food distribution centres run by private US contractors guarded by Israeli troops, local authorities said.

Witnesses blamed the shootings on Israeli troops who opened fire early in the morning as crowds of hungry Palestinians converged on two hubs managed by the Gaza Humanitarian Foundation (GHF), a private organisation that recently began operating in Gaza with Israeli and US support.

The death toll on Monday was the highest yet reported in the near-daily shootings since the GHF began operations three weeks ago.
