Qatar could close the political office of Hamas as part of a broader review of its role as a mediator in the war between Israel and the militant Palestinian Islamist group, according to an official familiar with the Qatari government's reassessment.

The Gulf state was weighing whether to allow Hamas to continue operating the political office, and the broader review includes considering whether or not to continue mediating in the seven-month conflict, the official told Reuters.

Qatar said last month it was reevaluating its role as a mediator in indirect talks between Israel and Hamas, citing concerns that its efforts were being undermined by politicians seeking to score points.

"If Qatar isn’t going to be mediating, they won’t see a point in keeping the political office. So that is a part of the reassessment," the official said, speaking on condition of anonymity.

The official did not know if Hamas would be asked to leave Doha if the Qatari government did decide to close the group's office. However, the official did say Qatar's review of its role would be influenced by how Israel and Hamas act during the ongoing negotiations.

In a report on Friday, The Washington Post cited an unnamed US official as saying Washington had told Doha to expel Hamas if the group continues to reject a ceasefire deal with Israel.
