ICC welcomes arrest of C Africa war crimes suspect

The International Criminal Court's chief prosecutor on Monday welcomed the arrest of an alleged militia commander in the Central African Republic, but said she remained "very concerned" about the country's volatile situation.

Mahamat Said Abdel Kani, an alleged leader of the Seleka rebel coalition, was handed to the court on Sunday and arrived at the ICC's detention unit in The Hague early Monday, court officials said.

Kani, 50, is suspected of committing crimes against humanity and war crimes including torture after the country spiralled into sectarian violence in 2013, following the ouster of former leader Francois Bozize.

The violence pitted the Seleka, a mainly Muslim-backed rebel coalition against mainly Christian vigilante self-defence groups known as anti-Balaka, which means anti-machete.
