Sudan's President Omar al-Bashir (L) smiles with Uganda's President Yoweri Museveni as he arrives at Khartoum Airport for talks during an official visit to Sudan September 15, 2015. The visit comes amid strained relations between Khartoum and Kampala as the two countries trade accusations of support to rebel groups. Sudan accuses Uganda of harboring rebel group members of the Sudanese Revolutionary Front (SRF) while Uganda claims that the rebels of the Lord Resistance Army (LRA) are in western Sudan.
