town, northeastern Gabon, on the Ivindo River where it receives the Liboumba and Mounianghi rivers. Pygmies live in the surrounding forest. The town lies in the heart of a major lumbering region, and, although it is rather isolated from the rest of the country, transportation is improving: a modern highway bridge spans the Ivindo, there is an airport, and the town is on the projected route of a northeast spur of the Trans-Gabon Railway. Pop. (1993) 9,849.
