A man with a gun was killed by police at an assisted living facility in the 3800 block of Walnut Avenue in Fremont after he took two people hostage, police said Friday night.
Israel on Monday handed over the bodies of 45 Palestinians, the Red Cross said, a day after militants returned the remains of three hostages.
Israeli Prime Minister Benjamin Netanyahu said he has ordered the army to immediately carry out "powerful strikes" in Gaza, in a new test for a U.S.-brokered ceasefire.
The Israeli military said Wednesday that one of the bodies handed over by Hamas the previous day as part of the ceasefire deal is not that of a hostage who was held in Gaza.
All 20 living hostages held by Hamas and hundreds of Palestinian prisoners held by Israel walked free Monday as part of a ceasefire pausing two years of war that decimated the Gaza Strip and killed tens of thousands of Palestinians.
The moment remains fragile, with Israel and Hamas still in the early stages of implementing the first phase of Trump's plan.
