The UAE accused Qatari fighter jets of "intercepting" a passenger plane en route to Bahrain on Monday, in an ongoing row over alleged airspace violations.
"Qatari fighter jets intercept an Emirati civilian aircraft during a routine flight to Manama in a flagrant threat to civil aviation safety and in a clear violation of international law," the UAE General Authority of Civil Aviation said.
"This is a routine flight that has all the required paperwork," it said in a statement published by the state news agency.
Four UAE-based airlines – Emirates, Etihad, flydubai and Air Arabia – operate flights to Bahrain.
Spokespersons for the airlines contacted by AFP could not immediately confirm or deny the news.
