British evacuation efforts in Sudan will be “potentially impossible” once a ceasefire ends, Foreign Secretary James Cleverly said.
Cleverly said there is no guarantee of further evacuation flights once an agreed halt in fighting expires on Thursday night.
It comes as the government faces domestic and international criticism over its response.
The British evacuation mission from the African country has seen 536 people taken to safety on six flights so far, according to the latest official figures.
“We cannot predict exactly what will happen when that ceasefire ends but what we do know is it will be much, much harder, potentially impossible,” he said.
“So what we’re saying to British nationals is if you’re hesitant, if you’re weighing up your options, our strong, strong advice is to go through Wadi Saeedna whilst the ceasefire is up and running.
“There are planes, there is capacity, we will lift you out. I’m not able to make those same assurances once a ceasefire has ended.”
More than 2,000 British nationals in Sudan have registered with the Foreign, Commonwealth and Development Office (FCDO) under evacuation plans, but thousands more could be in the war-torn nation.
“There are concerns the evacuation efforts have seen families split up or some members left behind.’’
