Rishi Sunak has held an emergency Cobra meeting to discuss helping British nationals trapped in Sudan.

Fierce fighting has taken place across the country since April 15 after tensions between the Sudanese army and RSF paramilitary force boiled over.

More than 400 people have been killed so far and at least 3,500 injured, according to the United Nations.

The country’s capital Khartoum remains at the epicentre of the fighting, with many residents stuck in homes without access to water and electricity.

Government officials have said they are ‘doing everything possible’ to support those trapped in the capital.

The Sudanese army has said they are coordinating efforts to evacuate American, British, Chinese and French citizens and diplomats from Sudan on aircraft.

Prospects of airlifting people out of the country have been complicated due to battlegrounds breaking out across airports.

An evacuation from the capital is expected to happen imminently with the British Army on standby.

The Ministry of Defence (MoD) is also planning for a wide range of scenarios, alongside the Foreign Office, on how it can assist in Sudan.

The MoD confirmed a high-readied armed forces unit is always ready to be deployed should they be required.

A UK Government spokesperson said: ‘We recognise that the situation is extremely concerning for British nationals trapped by the fighting in Sudan.

‘We are doing everything possible to support British nationals and diplomatic staff in Khartoum, and the Ministry of Defence is working with the Foreign Office to prepare for a number of contingencies.’

Those trapped in Sudan are advised to register with the FCDO and to stay indoors.

The Pentagon confirmed it is moving additional troops and equipment to a naval base in the Gulf of Aden to prepare for the evacuation of US embassy personnel.

But the White House has no plans for a government co-ordinated evacuation of an estimated 16,000 American citizens trapped in Sudan.

Rishi Sunak and the leader of Dijibouti have agreed to ‘continue to co-ordinate efforts to de-escalate the violence and protect civilians, including our citizens’.

Explosions and gunfire continue across the capital with an end to violence not yet in sight.

The Sudanese army has said it is coordinating efforts to evacuate foreign citizens and diplomats from Sudan on military aircraft.

Army chief Gen Abdel Fattah Burhan said he would facilitate the evacuation of American, British, Chinese and French citizens and diplomats from Sudan after speaking with the leaders of several countries that had requested help.

Fierce fighting and violence continues across Sudan.
