The Arab Gulf nation, a U.S. ally that has been a haven for Hamas leaders for nearly two decades, also said it will no longer host the Palestinian militant group’s political office, an official said.

The Gulf state’s move comes after more than a year of trying to leverage the group’s presence to broker a cease-fire with Israel.

The Gulf country has been working alongside the United States and Egypt for months on fruitless talks between the warring sides in Gaza and any disengagement from that process could further complicate efforts to reach a deal.
