At least nine people have been killed and several others injured in an Israeli attack in northern Gaza, the enclave’s ministry of health said Saturday, making it the deadliest incident since the ceasefire went into effect in January.

Witnesses said the people were in a car and on a mission for a charity in Beit Lahiya, and they were accompanied by journalists and photographers when the strike hit them.

Palestinian medics say Israeli airstrikes in the Gaza Strip killed at least eight people, including a local reporter who was operating a drone. The Indonesian Hospital said it received eight bodies from two airstrikes in the same area of the northern town of Beit Lahiya on Saturday.

Hamas said it would release Israeli-American soldier Edan Alexander if Israel started the next phase of ceasefire talks.

Hamas said it agreed to release Edan Alexander and turn over the bodies of four other hostages. But both the White House and Israel said Hamas wasn’t serious, suggesting a deal wasn’t close.
