UK diplomats and their families have been evacuated from Sudan after a “significant escalation in violence”, Rishi Sunak has said.
The prime minister also said he was working to ensure British citizens who are still stuck in the country are safe – as they appealed for help getting out.
He said the evacuation of diplomats and their dependents was “complex and rapid” and came amid threats to embassy staff in the capital Khartoum.
More than 1,200 British personnel from 16 Air Assault Brigade, the Royal Marines and the RAF were involved in the “difficult operation”.
Mr Sunak said he was “continuing to pursue every avenue to end the bloodshed” as he urged the warring sides to lay down their arms and “implement an immediate humanitarian ceasefire to ensure civilians can leave conflict zones”.
UK troops and military aircraft had earlier been moved to an overseas base to prepare for the high-risk rescue mission into an active conflict zone.
The British embassy in Khartoum has temporarily been closed as Foreign Secretary James Cleverly said UK diplomats were unable to carry out their functions because of the violence. He said they would be redeployed at other missions in the area.
He said a “temporary lull” in the fighting had allowed UK armed forces to make their move and help get the officials out.
Britons are appealing to be taken out of the country to escape the fighting.
Mr Cleverly said: “The safety and protection of British nationals in Sudan remains a priority for us – a top priority for us – and we will discharge that duty through our embassies based in the area in close coordination with our international friends and partners.”
He warned that until the conflict ends “we are severely limited in our ability to provide assistance to British nationals. I would say to British nationals in the region please register with us”.
