The self-styled prophet of a separatist sect blamed for deadly attacks in the Democratic Republic of Congo has been arrested in a raid on his home in Kinshasa involving hundreds of security forces. "Mission accomplished," a police tweet said, after troops stormed the home of former MP Ne Muanda Nsemi, who heads the Bundu Dia Kongo (BDK) sect, following an hours-long siege on Friday. A police source, speaking on condition of anonymity, said several BDK members were found in the house and added that an undisclosed number of people had died in the raid.
