Explosions at churches in Nigeria

Explosions hit two churches in the restive northern Nigerian city of Zaria Sunday, in the latest violence in the region, emergency services and residents said.

It was not immediately clear if there were any casualities, but residents said they feared many people had been killed.

The state-run National Emergency Management Agency (NEMA) said the blasts happened in the Wusasa and Sabon-Gari districts of Zaria, previously targeted by the Islamist group Boko Haram.

"NEMA has confirmed two explosions at Wusasa and Dabon-Gari in Zaria, Kaduna state. Rescue and security officers have moved to the scene," spokesman Yushau Shuaib said in a statement.

Residents said many people, mostly worshippers, were feared dead in the attacks on the Christ the King Catholic Cathedral and ECWA GoodNews Church.
