Two people said to be loyal to Burundi’s ruling party were killed late Friday.
According to Celestin Singirankabo, an official, an administrator of Gisozi commune in Mwaro province, 60 kilometres from the capital Bujumbura was one of the victims.
“Five people came around 9.30 p.m. and called the elected administrator by name and ordered him out of his house. They shot at him and he died,” he said.
“After that they moved to another nearby house and also shot another person,” he added.
He also said that three of the unidentified gunmen wore either police or army uniforms.
There has been a resurgence of violence in Burundi after a relatively peaceful month with at least five people killed and some 50 injured in several grenade attacks in the capital Bujumbura this month.
The East African country was plunged into chaos since April last year when President Pierre Nkurunziza vowed to run for a third term, sparking protests by the opposition who said his bid was unconstitutional.
The turmoil in the country has left more than 400 people dead while at least 230,000 have fled into neighbouring countries.
