Ten killed in Nigeria's Zamfara state

At least 10 people have been killed by cattle rustlers in the north-western Nigerian state of Zamfara.

Villagers said dozens of armed men arrived on motorbikes, shooting dead members of a vigilante group set up to guard the area.

They made off with several cattle.

Communities in the north-west live in constant fear of attack.

Many have set up vigilante groups, saying the security forces are incapable of protecting them.
