DUBAI: The United Arab Emirates will lodge a complaint against Qatar at the United Nations' aviation agency after Qatari war planes allegedly intercepted UAE civilian aircraft, a UAE official said yesterday. The UAE said on Monday that Qatari air force jets had intercepted two UAE civilian aircraft on routine commercial flights to Bahrain. Qatar has said the claims are "completely untrue". The UAE will accuse Qatar of violating the Chicago Convention, which governs the use of airspace, in a complaint to the International Civil Aviation Organization (ICAO), UAE General Civil Aviation Authority Director-General Saif Mohammed Al-Suwaidi told Reuters. He said the UAE aircraft had been intercepted in airspace managed by Bahrain. He declined to say whether their flight paths had taken them across Qatar, the most common route from the UAE to Bahrain.
