Sudan and four neighboring nations will hold a summit here this month to try to contain the two-year Darfur conflict. Egyptian Foreign Minister Ahmed Aboul Gheit said the leaders of Sudan, Egypt, Nigeria, Libya and Chad will attend the April 20 summit in Egypt's Red Sea resort of Sharm el-Sheikh. Aboul Gheit said the leaders of the five nations will discuss the Darfur conflict, plus the implementation of peace accords signed in Sudan's 23-year southern civil war in January. "The international community must be aware of the importance of not taking measures or decisions that might complicate the picture and lead to pressure on Sudanese society and provoke an unwanted international, regional, and Sudanese (outcome)," Aboul Gheit said Sunday. "The Darfur issue and the consecutive decisions that have been issued lately create a situation that might lead to complications," Aboul Gheit added.
