Mike Huckabee, the U.S. ambassador to Israel, demanded “accountability for this criminal and terrorist act,” referring to the killing last week of Sayfollah Musallet in the occupied territories.

Meanwhile, Israel and Hamas appeared no closer to a breakthrough in talks meant to pause the 21-month war and free some Israeli hostages.

Saif Musallet, a dual national, was reportedly attacked while traveling near his village. Eyewitnesses said he was dragged from his vehicle and assaulted by a group of settlers. He died on the spot.
