DUBAI - Qatar accused its neighbor Saudi Arabia of reckless behavior after a newspaper report that Riyadh had threatened military action if Doha installed a Russian air defense system.
Qatar's foreign minister told Al Jazeera he did not think the Saudi threat - reportedly made in a letter to France - was serious. But he accused Riyadh of using the letter to try and create a "disturbance" in a region already rocked by a year-long stand-off between Doha and other powers.
France's Le Monde
newspaper reported on Saturday that Saudi King Salman had sent a letter to French President Emmanuel Macron expressing concern over talks between Doha and Moscow about Russian S-400 missile air defense systems.
The newspaper added that the king had said Saudi Arabia was ready to consider all measures, including military action.
"We are seeking formal confirmation from the French government (about the letter)," Foreign Minister Sheikh Mohammed bin Abdulrahman Al Thani told the English-language channel of Qatar-based Al Jazeera in an interview aired on Tuesday.
"There is no serious military threat out of this, but the way it is being used to justify or to create a disturbance in the region is just unacceptable," he said. "There is no legitimate grievance behind this letter and threatening Qatar."
Saudi Arabia, Egypt, Bahrain and the United Arab Emirates severed diplomatic and economic ties with Qatar a year ago, accusing Doha of supporting terrorism. Qatar denies the accusation and says the boycott is an attempt to impinge on its sovereignty.
The French president's office and the Saudi government's communications office have not responded to requests for comment on the newspaper report.
Qatar and Russia signed an agreement on military and technical cooperation last year. Qatar's ambassador to Russia was quoted as saying in January that it was in talks to buy the Russian S-400 missile air defense systems.
Asked if Doha would go ahead with the deal, the foreign minister said: "Qatar made all the options open for its defense procurement, so we are seeking the best quality to defend our country and we have all the options open for this."
Sheik Mohammed described the Saudi move as "reckless behavior."
Washington has strong alliances with both sides and fears the split among Sunni Muslim US allies could benefit Shi'ite Muslim Iran.
