Karabakh conflict is one of the most complex challenges in the OSCE region, says the organization's annual report as of 2013.

"More than 20 years have passed since conflict broke out in Nagorno-Karabakh, but a lasting and comprehensive political settlement has yet to be achieved," the report reads.
 
Five civilians and 32 servicemen were reported shot and wounded in 2013 and another 14
servicemen killed. In that same period, Ambassador Kasprzyk’s team visited the Line of Contact 16 times, and the border nine times.
 
In 2013, his team also supported two visits to the region by the Chairman-in-Office and several by the Co-Chairs.
