A Saudi-led move to isolate Qatar has had “no impact” on U.S. military operations in the emirate, nor is any expected, a Pentagon spokesman said Tuesday.

The U.S. has a regional command center at Al-Udeid air base near Doha from which it runs air operations throughout the region.

“There has been no impact on our operations either in Qatar or with regards to airspace permission around it and we don’t anticipate there will be,” Pentagon spokesman Jeff Davis said.

He renewed praise of Qatar for hosting U.S. forces and its “enduring commitment to regional security,” sticking to a message of reassurance even as President Donald Trump, via Twitter, applauded a decision by Arab powers to cut ties to the Gulf ally.

Pentagon spokesman Navy Captain Jeff Davis declined to answer a question about whether Qatar supported terrorism, the accusation made by Arab states, saying: “I’m not the right person to ask that. I consider them a host to our very important base at al Udeid.”
