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.
Upper Karabakh, an internationally recognized territory of Azerbaijan, is under illegal Armenian occupation since 1991.
