A rift between Qatar and other Arab states is not affecting US military operations, the Chairman of the Joint Chiefs of Staff said on Tuesday.

"We are watching that very, very closely but we have had good cooperation from all the parties to make sure that we can continue to move freely in and out of Qatar," Joseph Dunford told a US Senate Armed Services Committee hearing.
The Pentagon said last week that after Saudi Arabia and its allies imposed economic and diplomatic boycott on Qatar, current US military operations against Islamic State had not been affected but it was "hindering" the ability to plan for long-term operations.
