Gunfire was heard in several locations. Reports from Kano suggest at least six people have been killed. The BBC's Mark Doyle is in Kaduna in northern Nigeria.

blasts

took place, at least five of those at police stations. One of the police stations is reportedly very, very badly damaged. It may have been some sort of car bomb, and it may be many more police stations, but as (I say) residents say at least six.

The militant Islamist group Boko Haram, which has carried out attacks across northern Nigeria in recent months, says it was behind the latest bombings.

France is

suspending

its training programme and joint military operations with the army of Afghanistan after a rogue Afghan soldier killed four French soldiers and wounded about 15 others. It's the second time in three weeks that French soldiers have been killed by men that they are trying to train. President Nicolas Sarkozy said he would consider an early withdrawal of French units from Afghanistan, but the US Secretary of State Hillary Clinton says she doesn't think that'll happen.
