YEREVAN, Armenia, Oct. 9 (Xinhua) -- Member countries of Eurasian military alliance Collective Security Treaty Organization (CSTO) and joint Armenian-Russian forces started military exercises in Armenia on Monday, the Armenian Defense Ministry said.
Around 2,500 troops from peacekeeping divisions, special forces and missile and air units active in CSTO countries are taking part in "Collaboration-2017" at the Baghramyan military training facility.
The joint military exercises came two days after the second phase of CSTO military drills "Search-2017" ended in Armenia. "Search-2017" kicked off in Russia's Rostov region on Oct. 3.
At a press conference on Monday, CSTO Secretary-General Yuri Khachaturov said the drills are conducted under the command of Russia's Southern Military District because certain weapons used during the exercises are solely Russia-owned.
"Collaboration-2017" will end on Oct. 13.
The CSTO, formed in 1992, consists of six members, namely Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia and Tajikistan, and two observers -- Serbia and Afghanistan.
