A 78-member Pakistan Army peacekeeping contingent has left Pakistan on the United Nations Mission in Sudan (UNMIS) by a chartered aircraft, said an official statement. The batch will replace soldiers as part of the routine annual relieve-rotation schedule. Brigadier Muhammad Yousaf saw them off at Allama Iqbal International Airport in Lahore. Pakistan has contributed over 1,500 troops to the mission. The UNMIS was set up as part of UN's Security Council Resolution 1590 on March 24, 2005. The mission began after the Comprehensive Peace Agreement was signed between the government of Sudan and Sudan People s Liberation Movement on January 9, 2005 in Nairobi, Kenya.
