Armenia posted pictures earlier of the wreckage of a plane it said was a SU-25 warplane shot down by a Turkish fighter jet on Tuesday. It named the pilot as Major Valeri Danelin.
Turkey and Azerbaijan have denied the plane was shot down.
"Both planes crashed into a mountain and exploded and were destroyed. This shows the Armenian military leadership is not providing accurate information to its citizens and the public," presidential aide Hikmat Hajiyev said.
