Twin car bombs hit a Protestant church in a major military establishment in Nigeria today a month after a church bombing in the same state killed at least seven people and injured more than a hundred others.

A suicide bomber rammed an SUV loaded with explosives into a Catholic church holding Mass on Sunday in northern Nigeria, killing at least seven people and wounding more than 100 others in an attack that sparked reprisal killings in the city, authorities and witnesses said.

An explosion has struck a city in central Nigeria, causing unknown injuries, police said.
