NAIROBI: At least four people have died in renewed clashes in Burundi, where tensions remain high following President Pierre Nkurunziza’s controversial re-election, officials and witnesses said on Wednesday. Police and witnesses said clashes erupted overnight in several parts of the central African nation’s capital Bujumbura, with the night marked by sporadic gunfire and explosions. Police blamed armed “insurgents” for the violence. “Two insurgents were killed this morning when they fired on police in Jabe (district) and their weapons were seized,” deputy police chief Godefroid Bizimana told this news agency, adding that search operations were ongoing. Two more bodies were found on Wednesday between the districts of Musaga and Kanyosha, witnesses and official sources said. “The security forces are carrying out a systematic search of the area to look for weapons,” Bizimana said.
