The CSTO Secretariat expresses serious concern over the aggravation of the situation on the Armenian-Azerbaijani border.

“The current situation does not contribute to normalizing the situation on the border of two neighboring states," one of which is CSTO member state Armenia, the statement noted.

"We emphasize the need for an immediate restoration of the ceasefire in the CSTO responsibility zone. We express our condolences to the families of the victims and wish the wounded a speedy recovery," the statement added.
