“U.S. officials unsealed charges Tuesday against senior Hamas leaders, accusing them of conspiring to provide material support to a terrorist organization, conspiring to murder Americans and conspiring to use weapons of mass destruction. The criminal complaint against Hamas leader Yehiya Sinwar and others was made public as U.S. diplomats are preparing to present Israel and Hamas with a final hostage release and cease-fire proposal, potentially as soon as this week. The charging document — filed under seal in February in federal court in New York — cites the group’s large-scale attack in southern Israel on Oct. 7, which killed approximately 1,200 people, including more than 40 Americans, and resulted in the taking of about 250 hostages. It doesn’t provide much new information about Hamas but describes a terrorist conspiracy by the group’s leaders dating back to 1997 “to kill nationals of the United States.””
