CIA chief William Burns has left Doha, the Washington Post reported on Friday after no progress has been made in the negotiations to reach a cease-fire and hostage exchange deal. A source told the paper that there are disagreements still in place over which of the hostages and which of the Palestinian prisoners would be released, the number of IDF troops that would remain in the Strip, the right of displaced Gazan residents to return to the northern areas, who would administer the border passages and the end to the war.
