Air combat drills, involving jets and helicopters, will continue in Baku, Nakhchivan, Ganja, Kurdamir, and Yevlakh until Aug. 10.
Ground exercises, meanwhile, are being held in Baku and Nakhchivan until Aug. 5 with artillery, armored vehicles, and mortars striking simulated targets.
The exercises come on the heels of a recent attack by Armenia on Azerbaijani troops in the northwestern Tovuz border region. At least 11 Azerbaijani soldiers -- including a major general and a colonel -- were martyred.
Azerbaijan blamed Armenia for the "provocative" actions, with Ankara throwing its weight behind Baku, and warning Yerevan that it would not hesitate to stand against any kind of attack on its eastern neighbor.
