Nigeria's Boko Haram crisis: Zaria bomb attack 'kills 20'

About 20 people have been killed in a suicide bomb in the city of Zaria, in north-western Nigeria.  

A suspected suicide bomber targeted civil servants at a government building in the city. 

Witnesses say workers had been queuing up seeking employment under Mr Buhari's administration when the bomb detonated in Zaria's Sabon Gare district. 

The governor of Kaduna state, El-Rufa'i, said the government is working with the security agencies to end the wave of militant attacks in the country.
