At least 143 people have been killed in multiple bomb blasts targeting security buildings in Nigeria's second largest city Kano last night.

Initial reports suggested seven people had been killed in the attacks but that figure has now risen to 143 after more than 100 bodies were taken to the morgue at Murtala Muhammed Specialist Hospital in the city centre.

The attacks on police headquarters and security services head offices prompted the government to impose a dusk-to-dawn curfew in the city - which has a population of more than 10 million people. Police spokesman Olusola Amore said in a statement: 'At the moment, seven casualties have been confirmed from different locations of the attacks.'

The statement added that the police 'are doing their best to bring the situation under control' and are 'appealing to members of the public to come forward with information on the identity and location of these hoodlums'.
