Anti-government protesters have resumed in some neighborhoods in Burundi's capital after residents accused the police of harassment.

Police have been disarming Bujumbura neighborhoods amid political tensions stemming from the president's disputed re-election in July.

Residents reported heavy gunfire overnight and Wednesday morning as police searched neighborhoods for firearms. In the volatile Musaga area, protesters threw stones at police as others ran to safety amid gunfire and loud explosions.

Musaga resident Hussein Abdallah said they were protesting because the police have been making arrests even if they fail to find illegal guns.

Burundi has been rocked by violence since it was announced in April that President Pierre Nkurunziza would run for a thirds term. He won re-election amid frequent street protests in which at least 100 people were killed.
