Prisoners line up inside Douala central prison in Cameroon Reuters

Cameroon news outlet Barnebi.com is reporting on a major fire at New Bell prison in Douala, the largest city in the French-speaking West African nation.

Facebook user Martin Camus Mimb uploaded this video, which purpotedly shows the structure ablaze and billowing smoke.

The Newbell prison was constructed in 1935 for a prisoner population of 800 inmates but today counts more than 3,500 amid harrowing conditions, Voice of America reported. In 2005, a Cameroonian journalist working for the BBC in London described the situations in the prison as "hell on Earth." In 2008, Reuters reported prison guards killed 16 inmates who were attempting to escape.
