(NewsNation) — Israel broke the ceasefire deal with Hamas last week, killing dozens of Palestinians, saying the strikes will intensify until all of the hostages are free.

The last living American hostage is Edan Alexander, a 21-year-old Israeli American. 

An Israeli Defense Force soldier born and raised in New Jersey, Alexander has been in captivity for more than 500 days since the war’s start on Oct. 7, 2023.

Edan’s father, Adi Alexander, spoke with NewsNation’s “Morning in America,” sharing that he knows nothing about his son’s whereabouts.

He called the latest Israeli strikes on Gaza “very disturbing.”

“We urge everybody to go onto the bargaining table and start talking again,” he said. “The question to Prime Minister (Benjamin Netanyahu), how do you plan to get the last hostage out without ending this endless war and without committing to the second phase of the deal? It’s a really open question and we should receive an answer for that.”
