Reports say militants have attacked two churches in northern and central Nigeria, killing and wounding a number of worshipers.
In Biu in Borno state, five gunmen opened fire, reportedly killing one woman and injuring three other people.
In the central city of Jos, a suicide bomber blew himself up outside a church, injuring several people.
There was no immediate word on casualties and no claim of responsibility.
But attacking churches has become a tactic of Islamist group Boko Haram, which is fighting to reinstate an ancient caliphate in northern Nigeria.
