The authorities in France have detained a man suspected of being a militant commander during Liberia's first civil war, in the 1990s.

The man - who police identified as a naturalised Dutch citizen, Kunti K - has been charged with crimes against humanity.

He is said to have fought for the United Liberation Movement of Liberia for Democracy (Ulimo), and is suspected of torture, murder, slavery, the use of child soldiers and cannibalism.

Around 250,000 people were killed in Liberia's civil war in the 1990s and many thousands more fled the fighting.
