Britain’s Sudanese community is demanding the government does more to help bring their relatives – including NHS doctors – back from Sudan.

Two planes were sent out from RAF Akrotiri in Cyprus to evacuate UK diplomats and their families from Khartoum, but other British citizens have not yet received support to leave the country.

The prime minister said the evacuation of the diplomats and their dependents was “complex and rapid” and followed threats to embassy staff in the capital.

Hundreds have died in a bloody conflict between the Sudanese army and a powerful paramilitary group known as the Rapid Support Forces.

NHS medics are some of those caught up in the violence.

The Sudanese Junior Doctors Association UK (SJDA-UK) said it was aware of 71 Sudanese NHS doctors currently trapped in Sudan “because of the ongoing conflict”.

It tweeted: “We are concerned for their safety and the safety of their spouses and children.”

About half of those doctors are believed to be British nationals.

Dr Shaza Faycal’s young children, brother and mother are in Khartoum and trying to return to the UK after travelling to Sudan for a holiday to celebrate Eid.

Dr Faycal, a trustee of SJDA-UK, said she was “quite stressed”, adding: “It’s literally war happening there. What we would like to see is all NHS doctors who are now trapped there with their families to be evacuated, as a form of priority.”

Despite the rain and the crowds that gathered for the London marathon, Sudanese protesters defiantly gathered outside Downing Street to try to put pressure on the government to help British citizens who are stranded in the country.

Mohammed Baraka, one of the demonstrators, said: “All my family is in Sudan and they are in a very serious condition.

“I’ve been speaking to my younger brother, he is literally imprisoned in his apartment – no electricity, no water supply and this morning the internet supply was disconnected.”

Mr Baraka added: “We want this war to stop now, and I mean now. If this war continues, Sudan will be finished.”

The Foreign Office has not yet confirmed how many British citizens are in Sudan.

Foreign Secretary James Cleverly said: ”I would say to British nationals in the region – please register with us.

“We have circulated a link so we know who is there, where they are, so if an opportunity arises, we can find a way of helping them.”
