A suspected gang of Islamist militants has attacked the village of Ncumbi in northern Mozambique, reports say.

About 10 fighters launched their raid on the village in the province of Cabo Delgado at about 01:00 local time, according to the independent Mediafax news service.

Looking for food, they proceeded to kill a local trader who refused to let them into his stall, it said.

Some of the attackers, including national and foreign citizens mainly from Tanzania, are now in police custody.
