Ulaanbaatar /MONTSAME/. Five officers of the Mongolian Armed Forces will leave for Ethiopia and Eritrea on Tuesday to perform unarmed duties as UN military observers. The officers will go to the countries for the first time on the basis of the invitation from the UN Peacekeeping Operation Department. There are 218 military observers from 38 different countries in Ethiopia and Eritrea. In 2000, the UN Security Council appealed to solve the armed conflict between Ethiopia and Eritrea, which originated in 1998, by peaceful means. The UN peacekeeping mission launched its activities in the countries in September 2000.
