American hostage Edan Alexander released by Hamas after more than 580 days in captivity

Hamas released the last living American hostage Monday, after he spent more than 580 days in captivity inside the Gaza Strip. 

Edan Alexander, a 21-year-old dual U.S.-Israeli citizen, will be received by a specialized Israel Defense Forces unit and is going to be brought to an initial reception facility in Re’im, where he will undergo preliminary medical and psychological evaluation by IDF Medical Corps personnel, an Israeli official told Fox News. 

"The Al-Qassam Brigades have just released the Israeli soldier holding American citizenship, Edan Alexander, following communications with the U.S. administration," Hamas said in a statement. "This comes as part of the mediators’ efforts to reach a ceasefire, open the border crossings, and allow the entry of aid and relief for our people in the Gaza Strip."

Secretary of State Marco Rubio said Monday that President Donald Trump "is fighting to secure the release of every American detained abroad" and "We won’t stop until this conflict is over and all our hostages are home." As news spread of his release, a crowd that gathered in Alexander's hometown of Tenafly, N.J., erupted in applause.

HAMAS CLAIMS IT WILL RELEASE AMERICAN HOSTAGE EDAN ALEXANDER 

Sue Gelsey, the interim CEO of the Kaplan JCC on the Palisades, told Fox News an estimated 3,000 had gathered in downtown Tenafly, some arriving as early as 5 a.m.

Trump, who is slated to depart Washington, D.C., on Monday for visits to Saudi Arabia, Qatar and the United Arab Emirates, said prior to Alexander’s release that it was "great news." 

Israel said its Prime Minister Benjamin Netanyahu held a meeting Monday with Trump’s special envoy to the Middle East, Steve Witkoff, and U.S. Ambassador to Israel Mike Huckabee. Netanyahu then called Trump today and thanked him for his assistance in securing Alexander's freedom.

Alexander’s family will await him at the Re’im facility, accompanied by their assigned officer from the Missing Persons and Hostages Headquarters. After the initial reunion, Edan and his family will be airlifted to Ichilov Hospital in Tel Aviv for continued care, the official also told Fox News. 

As an IDF soldier, Alexander also will be provided with a comprehensive support framework, including medical, psychological, and logistical assistance, facilitated by military professionals. 

Hamas first claimed on Sunday that it would release Alexander. 

Alexander’s mother Yael said on Thursday that she was feeling "[s]uch sadness and agony not knowing what the fate of your son is.  

"I have not been able to sleep. I am stuck in Oct. 7, even though it’s been 580 days. I used to enjoy Mother’s Day so much. We would all go to the city to a special restaurant, and I insisted the kids write me letters on this day. I have not been able to celebrate anything since this nightmare began," she added.

Raised in Tenaflym Alexander moved to Israel at 18 to volunteer for military service in the IDF’s Golani Brigade. He lived with his grandparents in Tel Aviv and at Kibbutz Hazor, where he was part of a group of lone soldiers. 

He was kidnapped on the morning of October 7 – a Saturday when he wasn’t required to remain on base. His mother was visiting from abroad, and like many lone soldiers he had the option to go home for the weekend. He chose to stay, not wanting to leave his fellow soldiers short-staffed on guard duty. 

Ayelet Samerano, the mother of hostage Yonatan Samerano, said Monday that the previous day was Mother's Day, and how "[a]round the world, mothers celebrated with their children."

"But for me – and the other mothers of the 59 hostages – it was just another day of nightmare. Yes, I am happy for the Alexander family. They will finally have their son Edan back. I thank President Trump and Steve Witkoff for this progress," she added. "But President Trump – please don't stop. This is only the first step. Do whatever is necessary to bring every last one home. The other 58 hostages have no time left. They are in hell. The living could be killed any day. The deceased – their bodies could be lost forever. They must all come home."
