Khartoum, the capital city of Sudan, is a large communications hub in Northeast Africa. Prior to the secession of the south in 2011, Sudan was the largest country in Africa. After decades of civil war, the country signed an agreement to separate the predominantly Christian south from the Muslim north, which had been seeking to become an Islamic state since the 1960s. Sudan is a ripe harvest field, home to hundreds of unreached people groups. As a major trade center, Khartoum is the seedbed for the nation.
