Three Russian journalists investigating a private military contractor called Wagner Group were ambushed and killed in the Central African Republic, reports BBC News.

The big picture: Those responsible for the ambush have not been identified. Wagner Group is a Russian paramilitary organization with contractors involved in conflicts all over the world, including the Syrian Civil War.
