The International Criminal Court has issued an arrest warrant for Sudan's Defence Minister Abdelrahim Mohamed Hussein for alleged crimes in Darfur.
The court said there were sufficient grounds to hold him responsible for 20 counts of crimes against humanity and 21 counts of war crimes.
In December, a senior Sudanese official dismissed the request for the warrant as "ridiculous".
The Hague-based ICC has already indicted Sudan's president.
The UN estimates that more than 300,000 people have died in Darfur, mostly from disease, since rebels took up arms in 2003.
