Russian-led military bloc sending team to Armenia

The Collective Security Treaty Organization announced on Tuesday that it will send a mission to Armenia to report on the situation in the southern Caucasus and propose solutions to the tensions with Azerbaijan. The mission will be led by CSTO Secretary General Stanislav Zas of Belarus and include Russian General Anatoly Sidorov, the head of the bloc’s joint staff.

The decision was made at a videoconference of the bloc’s Security Council convened by Armenia, which currently presides over the CSTO. Armenian PM Nikol Pashinyan informed the allies about the overnight border clashes with Azerbaijan. At least 49 Armenians and 50 Azerbaijanis were killed in the fighting, which involved heavy artillery and drones, according to the defense ministries in Yerevan and Baku.
