Such escalation is unacceptable – Warlick

The US co-chair of the OSCE Minsk group has published in his Twitter microblog a photo of a mortar thought to have been used by Azerbaijan’s military for shooting Armenian defense positions.

“This is a 120mm mortar reportedly used in the Nagorno-Karabakh conflict. Such escalation in unacceptable,” James Warlick tweeted.

Photos were earlier published also by the Nagorno-Karabakh Ministry of Defense.
