Suspected members of a militant group in the Democratic Republic of Congo have shot dead 16 people who were returning from a weekly market.

The ambush took place in the east of the country.

Hospital officials in the town of Oicha say the victims include six women and a child.

The attackers are believed to belong to the Allied Democratic Forces - one of several militias operating in eastern Congo.

The group is accused of having killed hundreds of civilians since the Congolese army launched an operation against them last year.
