6 Killed in series of explosions in Nigeria's Kano city

At least six people were reportedly killed in a series of explosions that rocked the Christian neighbourhood of Sabon Gari in Nigeria's second largest city, Kano.
Residents said that the attackers, suspected to be Boko Haram insurgents, carried out four big explosions yesterday targeting pubs on Enugu street.
Nigeria is fighting an Islamic uprising by extremists group Boko Haram based mainly in the northeast, where the government has declared a state of emergency.
The group has been blamed for coordinated suicide blasts at a bus park in Sabon Gari in March that killed at least 41 people.
Kano has been among the cities hardest hit during the Boko Haram's insurgency, even if in recent months it had seen a lull in attacks.

The insurgency is estimated to have killed more than 3,600 people since 2009, including killings by the security forces.
Aside from churches and other targets linked to the Christian community, Boko Haram has attacked the security forces, Muslim clerics and various symbols of authority.
