YEREVAN, January 23 (RIA Novosti) - A group of officials from the Organization for Security and Cooperation in Europe (OSCE) will monitor on Wednesday the contact line between Armenian and Azerbaijani troops on the border with the disputed Nagorno-Karabakh region, the Armenian Defense Ministry said.

The monitoring will take place near the village of Berqaber in Armenia’s Tavush region and will be supervised by Personal Representative of the OSCE Chairman-in-Office Andrzej Kasprzyk (Poland) and his field assistants, the ministry said.

The OSCE monitors the contact line between the troops on a regular basis as Armenia and Azerbaijan frequently accuse each other of violating the ceasefire agreement in the disputed area.

Skirmishes between the Armenian and Azerbaijani troops sometimes result in soldiers' deaths.

Relations between the two countries have been strained for more than two decades, since the conflict over Nagorno-Karabakh, a predominantly ethnic Armenian region, first erupted in 1988. The region then claimed independence from Azerbaijan to join Armenia.

Over 30,000 people are estimated to have died on both sides between 1988 and 1994, when a ceasefire was agreed. Nagorno-Karabakh has remained in Armenian control and tensions between Azerbaijan and Armenia have persisted.

The conflict over Nagorno-Karabakh is mediated by the OSCE Minsk Group that comprises the United States, Russia and France.
