Extra security around Christian churches in Iraq

There is extra security around churches and other Christian institutions in Iraq, in response to threats from a militant Islamist group linked to Al-Qaeda.

The group calling itself The Islamic State Of Iraq describes all Christians as "legitimate targets."

It says it was behind Sunday's attack on a Baghdad church which left at least 60 dead.

Explosions across the capital on Tuesday killed another 64 and injured nearly three hundred.
