Charity and aid groups said in a joint statement that more than 500 Palestinians had been killed and almost 4,000 injured in less than four weeks while trying to access or distribute food in Gaza.

More than 500 people have been killed in mass shootings near aid distribution centers or transport routes guarded by Israeli forces since the Gaza Humanitarian Foundation started operating.

Cairo — Dozens of international charities and non-governmental organizations, including Oxfam, Save the Children and Amnesty, called Tuesday for an Israeli and U.S.-backed aid mechanism for Gaza to disband over repeated incidents of chaos and deadly violence against Palestinians heading toward its sites.
