An Israeli hostage advocacy group on Saturday accused Prime Minister Benjamin Netanyahu of being the main obstacle to freeing captives in Gaza, hours after he blamed Hamas leaders for prolonging the war.

"The targeted operation in Qatar proved beyond any doubt that there is one obstacle to returning the ... hostages and ending the war: Prime Minister Netanyahu," the Hostages and Missing Families Forum said in a statement, referring to Israel's recent strike on a meeting of Hamas members in the Gulf state.

"Every time a deal approaches, Netanyahu sabotages it," they added.

Earlier in the evening, the premier had said eliminating Hamas' leaders in Qatar would bring an end to the war, accusing the group of derailing past efforts to secure a cease-fire.

"The Hamas ... chiefs living in Qatar don't care about the people in Gaza. They blocked all ceasefire attempts in order to endlessly drag out the war," he said on X.
