LAGOS, Nigeria — Gunman opened fire on a church in the northeastern Nigerian town of Biu, killing at least one person and wounding several others, a Christian official said, in the second such attack Sunday.

"One female worshipper was killed while several others were wounded, two of them critically," Christian Association of Nigeria chairman in Biu Samson Bukar told AFP. "The gunmen escaped after the attack."

The first attack Sunday took place in the central Nigerian city of Jos when a suicide bomber drove his car into a church, killing at least two people and wounding dozens more, officials and witnesses said.

"Forty-one wounded, the bomber and two others died," state government spokesman Pam Ayuba told AFP. The wounded were being treated at the city's Evangel Hospital, he added.
