The US Co-Chair of the OSCE Minsk Group on Karabakh said that if the sides truly wanted a negotiated settlement they had to reduce tension on the line of contact.
Both Armenia and Azerbaijan continue to claim daily violations of the ceasefire on the line of contact, but no casualties have been reported this week.
In a letter to the Minister of Justice the Council's Secretary General expressed concern about two recent attacks on Mammedov by fellow detainees.
Both sides report serious incidents within hours of the departure of the OSCE Minsk Group co-Chair, who were in the region trying to organise a meeting between the Presidents of Armenia and Azerbaijan
