RAF rescue flights plucking British nationals to safety from Sudan are due to start taking off from an airfield in the war-torn nation tonight.
But not all the estimated 4,000 Britons trapped in the African country will be rescued during a 72-hour ceasefire, it is understood.
Planners are looking at other options, including pulling some out by sea in a mission involving a Royal Navy Type 23 frigate, HMS Lancaster, and a Royal Fleet Auxiliary landing ship dock, Cardigan Bay.
