The conflict between Sudan's army and a paramilitary group called the Rapid Support Forces (RSF) has triggered a rush to evacuate foreign diplomats and citizens.
Several countries have taken nationals out by air, while some have gone via Port Sudan on the Red Sea, about 800 km (500 miles) by road from Khartoum. This is the status of some countries' efforts:
SAUDI ARABIA
Saudi Arabia, across the Red Sea from Sudan, has evacuated 5,197 people of 100 nationalities from Sudan, its foreign ministry said on Sunday. Evacuees included 184 Saudi citizens, it added.
UNITED STATES
U.S. forces evacuated American and some foreign diplomats on April 22.
A convoy organised by the U.S. government arrived at a Sudanese port city on Saturday, evacuating U.S. citizens, local staff and others, a U.S. State Department spokesperson said.
Washington has previously said it was positioning naval assets to assist evacuations if necessary.
BRITAIN
Britain said it has evacuated 1,888 people, mostly British nationals and their dependents, on 21 flights since Tuesday. The government decided the last evacuation flight would leave on Saturday evening, citing a decline in demand from British nationals and volatility on the ground.
The government had estimated there were about 4,000 Britons in Sudan. It evacuated its diplomats and their families on April 22.
Cyprus said it had activated a humanitarian rescue mechanism at Britain's request to let third countries use it for reception and repatriation of foreign citizens evacuated from Sudan. Cyprus is home to two large British military bases.

FRANCE
The French government said on Thursday it had so far evacuated 936 people, including Britons, Americans, Canadians, Ethiopians, Dutch, Italians and Swedes as well as French nationals.
The United Nations Secretary-General thanked France for its "vital assistance" in transporting 400 U.N. personnel and their dependents out of Sudan.

About 100 Dutch nationals have been evacuated from Sudan since April 23, Foreign Minister Wopke Hoekstra said. Half left on four Dutch evacuation flights to Jordan, which also carried about 70 people from 14 other countries.
