Hikmet Hajiyev, foreign policy adviser to Azerbaijan's President Ilham Aliyev, told Reuters that Azerbaijan's armed forces were conducting pre-planned drills in preparation for the autumn and winter, APA reports.
"It's part of the regular planning process," said Hajiyev, accusing Armenia in turn of concentrating troops on the border and of purchasing new weaponry systems.
He said ethnic Armenian forces inside Nagorno-Karabakh had also come out of their regular barracks and deployed to front-line positions in what he said was a high level of alertness.
"Our strategy is about deterrence and deterring any armed or illegal military actions or provocations against Azerbaijan," said Hajiyev.
