At least 12 Palestinians have been killed by Israeli forces while waiting for aid in central Gaza, according to rescuers and medics.

Reports say the group was killed by gunfire near an aid distribution site run by the US- and Israeli-backed Gaza Humanitarian Foundation (GHF) on Thursday.

The GHF denied there were any incidents near its site. The Israeli military told Reuters that "suspects" had attempted to approach forces in the area of Netzarim, and that soldiers had fired warning shots. It said it was unaware of any injuries.

The incident is the latest in almost daily shootings near such aid sites in Gaza.

Hundreds of Palestinians have been killed since late May, when the GHF took over aid distribution in Gaza in an attempt by Israel to bypass the UN as the main supplier of aid.
