Police in Sudan say they have arrested a number of suspects in connection with the murder of a Khartoum newspaper editor.
Sudan's official news agency cites a top police official, Major General Mohamed Najib al-Tayeb, as saying authorities continue their investigation into the murder of Taha Mohamed Ahmed.
Ahmed was found decapitated in southern Khartoum Wednesday, less than a day after he was kidnapped from his home.
Ahmed was editor of the newspaper al-Wifaq. Last year, Islamic radicals called for him to be killed after he published articles that questioned the roots of the Prophet Muhammad.
The editor of the Khartoum Monitor newspaper, Alfred Taban, has said he fears Ahmed's murder indicates the presence of extremist groups in Sudan.
