Qatar has withdrawn as a mediator for a Gaza ceasefire and hostage deal and has warned Hamas that its Doha office is no longer serving its purpose, according to a diplomatic source. Qatar, along with the United States and Egypt, has been engaged in unsuccessful negotiations for a truce and prisoner releases. The Qataris have informed both Israel and Hamas that they cannot continue to mediate as long as there is a refusal to negotiate in good faith. However, they have expressed their willingness to re-engage in mediation when both sides demonstrate a sincere willingness to return to the negotiating table.
