Which countries are evacuating citizens from Sudan?

As continued fighting raises fears that Sudan could plunge deeper into chaos, foreign governments are scrambling to get their diplomats and other citizens safely out. Most countries deployed military transport aircraft to fly people out, including France which used its airbase in neighboring Djibouti for the airlift. But not all is going smoothly - about 2,000 British nationals remain in Sudan, and many complain that their government isn't giving them enough information about evacuation plans.
