Trump hints at 'action' if Hamas doesn't return hostage bodies

The Israel Defense Forces “opened fire” at a vehicle that it says crossed the yellow line in northern Gaza.

IDF troops have withdrawn to an agreed-upon yellow line inside Gaza as a part of the first phase of the ceasefire deal. The IDF still controls more than 50% of Gaza after withdrawing to the yellow line.

“The troops fired warning shots toward the suspicious vehicle, but the vehicle continued to approach the troops in a way that caused an imminent threat to them,” the IDF said in the statement. "The troops opened fire to remove the threat, in accordance with the agreement."

New photos show Hamas members on Friday searching for the bodies of remaining Israeli hostages in Khan Younis in Gaza.

The bodies of 19 deceased hostages remain in Gaza. Hamas has handed over the bodies of nine deceased hostages this week and released all 20 living hostages. Releasing all hostages, including the deceased, is part of the ceasefire deal reached between Israel and Hamas.

Israeli Prime Minister Benjamin Netanyahu said that Israel could act if bodies of the hostages held by Hamas are not returned to Israel.

"I know exactly how many hostage bodies Hamas is holding and, if we don't receive them, Israel will know how to act accordingly," Netanyahu said on Thursday night.

"As the Prime Minister has emphasized, the 20-point plan enables all of Israel’s war objectives to be met once it is implemented. Namely, the dismantlement of Hamas capabilities, the demilitarization of Gaza and the deradicalization of radical Palestinians," said Ophir Falk, foreign policy advisor to Netanyahu.

"If it’s not implemented Israel will have to carry out more -- from a much better place than we were last week. Now that all the live hostages have been freed. Military operations will be much easier to carry out if needed,” said Falk.

Returning the bodies of the remaining hostages that are held in Gaza "may take some time," Hamas said Thursday.

The bodies are "buried in tunnels" that were destroyed by Israeli military action, Hamas said in a statement.

Israeli Prime Minister Benjamin Netanyahu and President Donald Trump discussed the "issue of the return" of the dead hostages during a phone call Thursday, Israeli hostage coordinator Brig. Gen. Gal Hirsch said in a statement to hostage families.

"The contact between us and the Americans and the mediators continues continuously, the pressure on Hamas continues and will intensify," Hirsch said.
