Russian Defence Minister Sergei Shoigu asked his Armenian colleague Vagharshak Harutyunyan to monitor the strict observance of the ceasefire in Nagorno-Karabakh, TASS reports.

'The main thing is strict adherence to the ceasefire regime in order to rule out provocations. I ask you to organise strict control over this,' Shoigu said at a meeting with Harutyunyan on Saturday.
