The UAE will lodge a complaint with the International Civil Aviation Organization after Qatari jets came within little more than three kilometres of Emirati passenger flights, its civil aviation chief said on Tuesday. 

"Today we will file our complaint to the International Civil Aviation Organization about the two serious incidents, along with the evidence that we've gathered, and ask for the intervention of the council to stop Qatar from repeating the act," Saif al-Suwaidi, head of the general civil aviation authority, told AFP.

The United Arab Emirates said on Monday that Qatari fighter jets had "intercepted" two passenger flights headed for Bahrain, drawing a swift denial from Gulf rival Qatar.
