Explosions, gunshots in northeast Nigeria city

Explosions and heavy gunfire echoed Saturday night through a city in northeast Nigeria that's home to a powerful politician, witnesses and officials said, the latest major attack in a region home to a radical Muslim sect.

It wasn't immediately clear if there were any casualties. The attacks began at 7:30 pm Saturday in the city of Geidam in Nigeria's Yobe state, which sits near the country's arid border with Niger, authorities said. (AP)
