There are about 80 missionaries and other private citizens in Burundi, where Maj. Pierre Buyoya seized power in a coup two weeks ago. The ousted president, Sylvestre Ntibantunganya, has taken sanctuary in the U.S. Embassy in Bujumbura.
The embassy remains open and at full staff, Nicholas Burns, the State Department spokesman, said Friday in issuing the travel advisory.
Rwanda has severed vital air and road links with Burundi, joining Tanzania, Kenya and Uganda in suspending ties until Burundi's new military-led regime accepts a regional peace initiative.
Burns advised the Americans to depart before sanctions halted all commercial flights and Americans would not be able to get out.
