Curfew in northern Nigeria after dozens killed in blast
A curfew has been imposed in the northern Nigerian state of Kaduna after multiple bomb attacks kill at least 36 people.
Officials said at least 16 people died and dozens were injured in the blasts.
Some 20 more people were killed in later rioting apparently targeting Muslims, aid workers and witnesses said.
No-one has yet claimed responsibility for the blasts, but Kaduna state has previously seen attacks by the radical Islamist group Boko Haram.
Kaduna state authorities have imposed a 24-hour curfew as soldiers and police try to restore order.
