Gunmen have opened fire on Muslim worshipers as they were leaving a mosque in northern Nigeria, killing at least 20 people, a local official said.
The attack on Sunday happened in a remote village called Dogo Dawa, in Kaduna state, said Abdullahi Muhammad, the traditional ruler and councillor of Birnin Gwari, a local government area next to the village.
The state police commissioner Olufemi Adenaike confirmed the incident, but did not give a death toll. There was no immediate claim of responsibility for the attack.
Like much of northern Nigeria, Kaduna is plagued by an insurgency led by radical Islamist sect Boko Haram. They usually attack security forces, government officials or Christians, but have hit Muslim clerics and mosques in the past, especially ones that do not follow their brand of Islam.
