Negotiators were trying to clinch agreement on Tuesday on the final details of a ceasefire in Gaza after marathon talks in Qatar, with mediators and the warring sides both saying a deal was closer than ever.

The truce will begin at 8:30 a.m., according to the Foreign Ministry of Qatar, a mediator in the talks. U.S. and other diplomats see the deal as the best chance to end the 15-month war that has devastated Gaza.
