The Levant News — The emergence of an online video of two US soldiers joking near a Qatari flag is causing tensions between Qatar and the United States. US Ambassador Dana Shell Smith, summoned over the incident, apologized to the Qatari Foreign Ministry and on Twitter to the people of Qatar. “Rest assured that these soldiers made fun of themselves and not of the state of Qatar,” Smith said in a tweet in Arabic. Pentagon spokesman Peter Cook said appropriate action will be taken as an investigation into the matter has been launched. Qatar is home to the largest US air base in the Middle East, at Al Udeid, where some 10,000 military personnel are stationed.
