GAZA - At least 12 Palestinians were killed on Sunday by Israeli airstrikes and gunfire across the Gaza Strip, including civilians near humanitarian aid distribution sites, according to local health officials.

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.

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.

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.

Hundreds of U.S. Marines arrived in the Los Angeles area by Tuesday under orders from President Donald Trump, who has also activated 4,000 National Guard troops to quell protests in the city despite objections from California Governor Gavin Newsom and other local leaders.
