Multiple explosions rocked a Christian area in Nigeria's northern Kano city on Monday night, with security forces ferrying scores of wounded to hospitals.
A mortuary attendant at Murtala Mohammed Specialists Hospital said at least 10 bodies had been brought in from the scene. He spoke on condition of anonymity because he was not authorised to speak to reporters.
Witness Kolade Ade said at least one blast appeared to come from a Mercedes-Benz parked beside a kiosk selling alcohol and soft drinks.
"After the first bomb, I threw myself into the canal (drain) to hide. There were at least three blasts," he said.
The explosions came as hundreds of people thronged the area in Sabon Gari neighborhood, where some were playing snooker and others table tennis.
The explosions raised fears among the city's mainly Muslim population, who usually go out for midnight prayers during this holy month of Ramadan.
Nigeria's government is fighting an Islamic uprising by a network called Boko Haram, which means "Western education is forbidden."
The group wants Islamic law imposed on Nigeria, Africa's most populous nation of more than 160 million, which is divided almost equally between Christians who live mainly in the south and Muslims who dominate the north.
