The military practicalities of providing what would, to all intents and purposes, be an armed escort from multiple points around Khartoum and the surrounding areas to a single point of exit, proved insurmountable. That was true for our international partners as well as ourselves—no country in the world was able to provide that level of security arrangement. We kept under review the safety of the various routes from within Khartoum to Wadi Saeedna, and we advised on that accordingly. I have a huge amount of admiration for the military personnel who sustained the longest airhead of any western nation at Wadi Saeedna and are currently supporting British nationals and others in their evacuation through Port Sudan.
