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.

Doha believes that Hamas and Israel have not demonstrated a "sincere willingness" to negotiate terms amid the ongoing war.

Qatar will stop trying to mediate a Gaza ceasefire deal until Hamas and Israel "demonstrate a sincere willingness to return to the negotiating table", an official briefed on the matter told Reuters on Saturday.

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.
