Qatar has withdrawn as a key mediator for a Gaza ceasefire and hostage deal and warned Hamas that its Doha office “no longer serves its purpose”, a diplomatic source told . “The Qataris informed both the Israelis and Hamas that as long as there is a refusal to negotiate a deal in good faith, they cannot continue to mediate […] As a consequence, the Hamas political office no longer serves its purpose,” the source said on condition of anonymity.
