Nigeria rocked by church blasts

Bomb blasts targeting Christmas Day church services in two Nigerian cities have left at least 28 people dead, with three more attacks on other towns.

The Islamist group Boko Haram said it had attacked St Theresa's Church in Madalla, near the capital Abuja, killing 27 people.

A second explosion shortly after hit a church in the central city of Jos. A policeman died during gunfire.
