The deadline has passed for British nationals to arrive at Port Sudan for what is being billed as the last evacuation flight to leave the country as a fragile ceasefire holds.
The Foreign, Commonwealth and Development Office (FCDO) had given those looking to flee the war-torn nation until 11am UK time - midday in Sudan - to reach the departure site on the eastern coast.
Officials at the Foreign Office would not confirm what time the flight was due to take off, but flight tracking websites showed a Royal Air Force (RAF) Airbus A400M Atlas plane as having landed at Port Sudan at about 3pm on Monday.
The UK government said it was “exceptionally” offering one final flight for a limited number of British nationals still in the country.
It comes as a UN official said more than 800,000 people may flee the war-torn country.
The UN Assistant High Commissioner for Refugees, Raouf Mazou, said: “In consultation with all concerned governments and partners we’ve arrived at a planning figure of 815,000 people that may flee into the seven neighboring countries.”
