The OSCE Minsk Group Co-Chairs have addressed the OSCE Chairman-in-Office a request for the structure special mission to draw a report on the situation at the contact line between the armed forces of Nagorno Karabakh and Azerbaijan. It was reported by the Office of Special Representative of the OSCE Chairman-in-Office Andrzej Kasprzyk in Tbilisi. As reported by the source, the Co-Chairs are seriously concerned over the periodical breaks of the cease-fire regime at the front line lately. "The situation is clear and simple: the cease-fire agreement is being broken and this should be cut short. The tension at the front causes the concern of the countries co-chairing the Minsk Group. This also prejudices the OSCE mediation activities," A. Kasprzyk office reported.
