Israel said Monday that Hamas had yet to clarify whether 34 hostages it said it was ready to free were dead or alive, throwing doubt on the group's assertion that it needed time to ascertain their fate.

A self-described struggling artist from Missouri, Jacob Burmood says he could have used the $3,500 offered by a South Florida suburb to exhibit one of his abstract metal sculptures. Florida is among more than 30 states that block government agencies from hiring companies that boycott Israel.

Israel and Hamas wrangled on Sunday over the details of a deal to halt fighting in the Gaza Strip and return hostages home, as Palestinian officials said intensified Israeli bombardments had killed more than 100 people over the weekend.

Israeli forces have killed a member of the Palestinian security services in the occupied West Bank whom they accused of being militant.

Media outlets say the Islamic group Hamas has agreed to release 34 hostages during the first phase of a potential ceasefire.

The deal would secure release of a third of the approximately 100 hostages who remain in Gaza, including two dual U.S.-Israeli nationals. In return, Israel would release some Palestinian prisoners.

The strike hit a tent in an Israeli-declared humanitarian zone known as Muwasi, where thousands of displaced people are sheltering.

Israel said Monday that Hamas had not yet provided the status of 34 hostages the group declared it was ready to release in the first phase of a potential exchange deal.

“As yet, Israel has not received any confirmation or comment by Hamas regarding the status of the hostages appearing on the list,” he said. “Israel will continue to act relentlessly for the return of all of our hostages.” At least two of the 34 people are dead, a Hamas official said.

With the deadline looming for the terms of a fragile cease-fire between Israel and Hezbollah to be met, an American diplomat on Monday said “much progress” had been made recently.
