The Collective Security Treaty Organisation (CSTO) announced that the organisation's military exercises will take place at the Harb Maidon training centre in Tajikistan, close to the Afghan border.
According to the organisation's statement, the drill will practise fighting illegal armed groups that are planning to attack the region.
According to the statement, the deployment of Russian, Kazakh and Kyrgyz forces to Tajikistan for the exercise began on October 11 and will continue until October 14.
The organisation has released a video of its military deployment to Tajikistan. In these pictures, a convoy of tanks and a variety of military vehicles can be seen.
Regional organisations, including the Collective Security Treaty Organisation (CSTO), have repeatedly expressed concern over the past three years about the risk of extremism spreading from Afghanistan to Central Asia.
Kazakhstan holds the presidency of the Collective Security Treaty Organisation (CSTO) this year and hosted another military exercise from member states this month.
Earlier, representatives from more than 40 countries expressed concern over the growing spread of extremism, radical religious teachings and racial discrimination in various countries. At a meeting in Moscow, they warned that the situation could lead to catastrophic consequences.
