At least 16 refugees died and 56 have been injured in an ambush on a train in Angola.
After the train hit a landmine on Friday, an unknown number of armed men fired indiscriminately at survivors of the explosion, the Lusa news agency quoted witnesses as saying.
The train was carrying more than 500 refugees fleeing fighting between government and UNITA rebel forces, and the number of dead could be much higher, authorities said.
The train was ambushed 100 miles south-east of Luanda in Cuanza Norte province.
More than three million people - about a quarter of Angola's population - have been driven from their homes by the war that has raged for almost all of the 26 years since Angola achieved independence from Portugal.
