A 24-hour curfew is in place in Nigeria's northern city of Kano, after co-ordinated bomb attacks killed at least seven people.

Police stations and the state police HQ were among the targets, and gunfire was heard across the second biggest city.
The militant Islamist group Boko Haram, whose name means "Western education is forbidden", said it was responsible.
The group has been behind a recent campaign of violence in the mainly Muslim north.
Meanwhile, organisers of a controversial civil activists' mass rally set for Saturday in the commercial capital Lagos called off the event in light of the attacks.
Organisers of the demonstration against government corruption and the military's presence in Lagos say they fear their protest could be infiltrated by militants sent to cause mayhem and cost more lives.
