The Head of Henaket analytical center Tigran Abrahamyan commented on the operation of Russian-Turkish monitoring center of the Nagorno-Karabakh ceasefire launched on January 30. 

"The fifth provision of the trilateral statement signed by Russian, Azerbaijani and Armenian leaders came into effect which envisaged a  peacekeeping center to be deployed to monitor the ceasefire. This will be carried out by Russia and Turkey and comes as another provision damaging Armenia's interests. It directly ensures Turkey's participation and that takes effect," Abrahamyan wrote. 

In the words of the expert, the development comes amid the fact that one of the priority provisions for Armenia which is the  exchange of prisoners of war, hostages and other detained persons has still been implemented partly.  

"According to different source, some 150 people are held in Azerbaijani captivity, and Azerbaijan uses this circumstance as a tool for pressure to get more concessions and, why not, mocking us" added Abrahamyan.
