The reported use of “drones” above or across the Nagorno-Karabakh line of contact is a provocation, OSCE Minsk Group Co-Chair James Warlick said.

“The sides need to reduce tension,” he tweeted.

On Thursday Azerbaijani armed forces reported about shooting down an alleged Armenian drone.

In turn, the spokesperson for Armenian Defense Ministry Artsun Hovhannisyan said Azerbaijani armed forces managed to shot down their own drone.

“According to reliable data, the Azerbaijani side shot down their own drone. 'Colleagues' from Azerbaijan are confused, and new reports will appear soon,” he wrote on Facebook.
