An unspecified number of people have reportedly been killed at St Phillip’s Catholic Church in Ozubulu, a town in Anambra state.

A witness said some gunmen, who concealed their identities with masks, broke into the church around 6am when the first mass service was holding.

Security personnel have cordoned off the church, which has since been deserted by worshippers.

Willie Obiano, governor of the state, Garba Umar, commissioner of police in Anambra, have visited the scene of the attack.
