Nigeria: Gunmen attack churchesGunmen in Nigeria have attacked two churches during Sunday services, killing and wounding worshippers.
In the central city of Jos, a suicide bomber blew himself up outside a church, killing at least two people and wounding dozens more.
Five gunmen opened fire in Biu in Borno state, killing one woman and injuring three other people.
No-one has admitted the latest attacks, but radical Islamic sect Boko Haram has targeted churches before.
One witness at the church in Biu said that "gunmen came to the premises of the church and started firing at people outside the church before going into the main building to carry on their killings", Reuters news agency reported.
"Many people have been killed and wounded," witness Hamidu Wakawa was quoted as saying.
