UNOMIG was originally established on 24 August 1993 by Security Council resolution 858 (1993) to verify compliance with the 27 July 1993 ceasefire agreement between the Government of Georgia and the Abkhaz authorities in Georgia with special attention to the situation in the city of Sukhumi; to investigate reports of ceasefire violations and to attempt to resolve such incidents with the parties involved; and to report to the Secretary-General on the implementation of its mandate, including, in particular, violations of the ceasefire agreement. The authorized strength of the Mission was 88 military observers.

After UNOMIG's original mandate had been invalidated by the resumed fighting in Abkhazia in September 1993, the Mission was given an interim mandate, by Security Council resolution 881 (1993) of 4 November 1993, to maintain contacts with both sides to the conflict and with Russian military contingent, and to monitor and report on the situation, with particular reference to developments relevant to United Nations efforts to promote a comprehensive political settlement. Following the signing, in May 1994, by the Georgian and Abkhaz sides of the Agreement on a Ceasefire and Separation of Forces, the Security Council, by its resolution 937 (1994) of 27 July 1994, authorized the increase in UNOMIG's strength to up to 136 military observers and decided that the mandate of an expanded Mission shall be as follows:

• To monitor and verify the implementation by the parties of the Agreement on a Ceasefire and Separation of Forces signed in Moscow on 14 May 1994;


• To observe the operation of the peacekeeping force of the Commonwealth of Independent States (CIS) within the framework of the implementation of the Agreement;
• To verify, through observation and patrolling, that troops of the parties do not remain in or re-enter the security zone and that heavy military equipment does not remain or is not reintroduced in the security zone or the restricted weapons zone;
• To monitor the storage areas for heavy military equipment withdrawn from the security zone and the restricted weapons zone in cooperation with the CIS peacekeeping force as appropriate;
• To monitor the withdrawal of troops of the Republic of Georgia from the Kodori Valley to places beyond the boundaries of Abkhazia, Republic of Georgia;
• To patrol regularly the Kodori Valley;
• To investigate, at the request of either party or the CIS peacekeeping force or on its own initiative, reported or alleged violations of the Agreement and to attempt to resolve or contribute to the resolution of such incidents;
• To report regularly to the Secretary-General within its mandate, in particular on the implementation of the Agreement, any violations and their investigation by UNOMIG, as well as other relevant developments;
• To maintain close contacts with both parties to the conflict and to cooperate with the CIS peacekeeping force and, by its presence in the area, to contribute to conditions conducive to the safe and orderly return of refugees and displaced persons.

The Human Rights Office forms part of UNOMIG and reports to the High Commissioner for Human Rights through the Head of Mission of UNOMIG.

  Most recently the mandate of UNOMIG was extended until 31 January 2003 by Security Council resolution 1427 (2002) of 29 July 2002.
