An Israeli delegation left for Qatar on Sunday for talks on a possible Gaza hostage and ceasefire deal, an Israeli official said, hours before Prime Minister Benjamin Netanyahu was due to head to Washington to meet U.

Israel made it clear it will not agree for Qatar to solely have exclusive control over the rehabilitation funds, but will request that additional countries participate in the effort.

An Iranian missile strike on Al-Udeid Air Base in Qatar last month hit a critical communications structure used by the US military.

U.S.-led ceasefire efforts in Gaza appear to be gaining momentum after nearly 21 months of war, as Prime Minister Benjamin Netanyahu’s office says Israel on Sunday will send a negotiating team to talks in Qatar.
