Qatari officials have told Hamas political leaders they are no longer welcome in the country, U.S. and Israeli officials said over the weekend, given the deadlock between Israel and Hamas on cease-fire talks to end the war in Gaza.

The Qatari government declined to comment. But an official familiar with the matter said Qatar had decided that the political office maintained by Hamas in the capital, Doha, no longer served its purpose because of the stalled the truce negotiations.

The Qatari move appeared to be an attempt to ramp up pressure on the Palestinian armed group and Israel to compromise on terms for a cease-fire that would also free the remaining 101 hostages held in Gaza. But it was unclear whether Qatar would immediately enforce a decision to expel Hamas leaders from Doha and if so, how long it would last.

A key mediator between Israel and Hamas, Qatar also informed both sides that it was stepping back from the moribund cease-fire talks, said the official, who like others spoke on condition of anonymity to discuss sensitive negotiations.

Qatar has hosted Hamas’s exiled political leaders since 2012, making Doha a focal point for negotiations with Israel to end the war in Gaza and free the remaining hostages held there. Egypt, which borders Gaza, is the other major mediator between the two sides.

Hamas officials did not respond to requests for comment.

Hamas has long insisted on a permanent end to the war and a complete Israeli withdrawal from Gaza before releasing any of the remaining hostages. Benjamin Netanyahu, the Israeli prime minister, has vowed to continuing fighting until Hamas’s destruction in Gaza and suggested Israeli forces would have to remain in parts of the enclave during a cease-fire.
