YEREVAN, November 15. /TASS/. Armenia’s refusal to take part in events hosted by the Collective Security Treaty Organization (CSTO) threatens the country’s security, Seyran Ohanyan, head of the "Armenia" parliamentary opposition faction and ex-defense minister, said at a briefing.

"As threats surround us in a complicated military and political situation, not taking part in CSTO events puts Armenia’s security at further risk. We are a member of this alliance. In many cases, Armenian authorities played a part in the deterioration of relations," he noted, commenting on Armenian Prime Minister Nikol Pashinyan’s refusal to participate in a CSTO Council meeting scheduled to be held in Minsk on November 23.
