A shooting near Israeli- and US-supported food distribution points in the Gaza Strip left at least eight Palestinians dead Sunday, according to health officials.

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 methods.

Palestinians say Israeli forces opened fire on people trying to access a U.S.-backed group's aid distribution hub in Gaza, in the deadliest of such incidents reported to date.

Shootings have erupted nearly daily since last week in the Gaza Strip in the vicinity of new hubs where desperate Palestinians are being directed to collect food. Witnesses say nearby Israeli troops have opened fire.

At least 27 Palestinians were reported to have been killed on the morning of June 3 amid chaotic scenes at an aid distribution centre in the southern Gaza Strip. This follows a similar incident on June 1 when around 30 civilians were reportedly killed as people scrambled to get food supplies at an aid centre near Rafah in southern Gaza.

At least 27 Palestinians were killed near a Gaza food distribution hub operated by a controversial U.S.-backed group, the enclave's Hamas-run health ministry says.

A CNN investigation into a deadly incident near an aid distribution site in southern Gaza on Sunday points to the Israeli military opening fire on crowds of Palestinians as they tried to make their way to the fenced enclosure to get food.

After three consecutive days of violence, aid has been paused in Gaza, the U.S. and Israel-backed Gaza Humanitarian Foundation announced. Dozens have been killed while trying to pick up food at a designated checkpoint.

Global Affairs Canada again called on Israel to allow the United Nations to resume humanitarian work in Gaza after days of shooting incidents at aid distribution sites.

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.
