President Joe Biden cheered the announcement of the ceasefire and hostage deal, and credited “dogged and painstaking American diplomacy” for landing the agreement, while claiming a measure of credit in the breakthrough moment in the 15-month war.

“I laid out the precise contours of this plan on May 31, 2024, after which it was endorsed unanimously by the UN Security Council,” Biden added in a statement. “My diplomacy never ceased in their efforts to get this done.”

Biden’s comments came not long after President-elect Donald Trump in a social media post claimed his election victory is what brought about the deal.

Qatar’s prime minister on Wednesday announced a ceasefire agreement between Israel and Hamas that will pause the devastating 15-month war in Gaza and clear the way for dozens of Israeli hostages to go home. Sheikh Mohammed bin Abdulrahman Al Thani announced the agreement in the Qatari capital of Doha, the site of weeks of painstaking negotiations. He said the deal would go into effect on Sunday.

Three officials from the U.S. and one from Hamas confirmed that a deal had been reached, while the office of Israeli Prime Minister Benjamin Netanyahu said final details were still being ironed out.

All three U.S. officials and the Hamas official requested anonymity to discuss the contours of the deal before the official announcement by mediators in Doha.

Netanyahu’s office said in a statement that it hoped “details will be finalized tonight.” Any agreement needs to be approved by Netanyahu’s Cabinet.

Once official, the deal is expected to deliver an initial six-week halt to fighting that is to be accompanied by the opening of negotiations on ending the war altogether.

Over six weeks, 33 of the nearly 100 hostages are to be reunited with their loved ones after months in in captivity with no contact with the outside world, though it’s unclear if all are alive.
