Sudanese anti-aircraft crews opened fire on an aerial "target" near Khartoum's twin city of Omdurman, a military spokesman said on Wednesday, after witnesses reported hearing explosions in the area. Air defence forces at Omdurman's Wadi Sayidna military area "confronted a lit-up target late yesterday (Tuesday) evening, showing their vigilance and readiness to repulse any enemy target," Colonel Al-Sawarmy Khaled Saad said in a statement. Witnesses in Omdurman said they heard loud explosions from outside the city late on Tuesday. The area is home to several military installations.
