The UN human rights chief said Israel's "means and methods of warfare" were inflicting "horrifying, unconscionable suffering".

Health officials say at least eight Palestinians were killed and dozens more were wounded in the latest shooting near Israeli- and U.S.-supported food distribution points in Gaza.

Israeli fire killed at least 40 people, half of them near an aid distribution site operated by the U.S.-backed Gaza Humanitarian Foundation on Monday, the territory's health ministry said, as U.N. officials denounced Israeli-backed aid delivery.
