Context
Omdurman sits on the west bank of the Nile, facing Khartoum. North of the city lies the Wadi Sayidna military zone and Wadi Seidna Air Base, about 22 km north of Khartoum. Sudan had reasons to watch its skies. Israeli strikes had been reported on a convoy in eastern Sudan in March 2009. In October 2012 the Yarmouk arms factory in Khartoum was struck, and Sudan blamed Israel.
