A body Hamas returned to Israel as part of President Trump's ceasefire deal is not that of any of the hostages, the Israel Defense Forces said Wednesday.

CAESAREA, Israel — Ten years ago this week, two Palestinian attackers boarded a bus in Jerusalem where they shot, beat and stabbed Israeli-American educator Richard Lakin to death along with two others before police killed one of the militants and injured and arrested the other.

Gaza is in ruins, and the bodies of 21 Israeli hostages are somewhere amid the rubble, along with an estimated 11,000 Gazans.

As senior Israeli officials accuse Hamas of stalling the implementation of the peace agreement, senior U.S. advisers said that the fragile peace deal that ended the war in Gaza seems to be holding, noting that Hamas is making every effort to return the remaining hostage bodies.

With the bodies of 10 people returned from Gaza, Israelis elated by the release of hostages began mourning those who did not make it home alive.

National Education Association teachers union distributed antisemitic course materials that included Palestine map replacing Israel and Hitler-praising content.

Hamas released all 20 living Israeli hostages Monday, and Israel released more than 1,900 Palestinian prisoners as part of a ceasefire in the Gaza Strip. U.S. President Donald Trump visited the region to discuss postwar plans.
