Nigeria Owo church attack: 'I received a call, my brother died'

Gunmen have killed an unknown number of church worshippers in Ondo state, south-west Nigeria.

The armed men entered St Francis Catholic church in the town of Owo and fired at the congregation during a service to mark the holiday of Pentecost, witnesses said.

The BBC's Andrew Gift is on the church grounds where bereaved relatives of the casualties are gathering.
