At least 80 people have been killed in two suicide bombings in Nigeria.

Both happened in the town of Kaduna. One targeted a convoy carrying Nigeria’s main opposition leader ( ex-president Muhammadu Buhari), the other a moderate cleric ( Sheikh Dahiru Bauchi).

Neither was injured.

The blasts bear the hallmarks of the Islamist militant group Boko Haram which has been active northern Nigeria but now appears to be spreading its attacks across the country.

A curfew was put in place in Kaduna by the town’s governor who condemned the bombings as the ‘height of cowardice’.

The attacks have taken place 100 days after the kidnapping of more than 200 girls from their school in the remote northeastern town of Chibok by the Islamists.

The insurgents who are fighting to carve out an Islamic state in Nigeria, have repeatedly targeted civilians. They have killed more than 2,000 during the first half of this year, according to Human Rights Watch.

To mark the 100 days the girls’ parents held a special commemoration ceremony in the capital Abuja with supporters of the “Bring back our girls” campaign.

Many Nigerians are unhappy with the government, accusing politicians of not doing enough to get the girls released.
