Qatar has told Palestinian militant group Hamas and Israel it will stall its efforts to mediate a Gaza ceasefire and hostage release deal until they show "willingness and seriousness" to resume talks, its foreign ministry said on Saturday.

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.

The Qatari ministry also said press reports on the future of the Hamas political office in Doha were inaccurate without specifying how. On Friday a U.S. official said Washington had asked Qatar to expel the group and that Doha had passed this message on to Hamas.
