A Burundi state TV cameraman and his family have been killed in the capital Bujumbura by police who say they were trying to free kidnapped colleagues.
The police said 10 people were killed in the incident, including cameraman Christophe Nkezabahizi, his wife and two children and one policeman.
Gunfire and grenade explosions were heard throughout the night.
Unrest began in April when President Pierre Nkurunziza announced he would seek a third term in power.
Burundi has been hit by a wave of unexplained killings in recent months, of both opposition activists and security officials.
In September, Burundi’s army chief of staff survived an assassination attempt. Earlier in the same week a spokesman for a party opposed to President Nkurunziza’s third term was shot dead in Bujumbura.
It is not clear who kidnapped the police officers in the latest incident.
