Qatar is suspending its role as a mediator in talks between Israel and Hamas after concluding that the two sides are no longer negotiating in good faith, two sources familiar with the situation tell CNN.

Qatar has served as a key mediator between Israel and Hamas since the Oct. 7 Hamas attacks. But the Gulf monarchy has also come under scrutiny for its ties to the terrorist group, since many senior Hamas leaders reside in Doha. Negotiations have continued off-and-on since last November’s hostage deal, which resulted in the release of 105 hostages.
