At least 20 people have been killed and many others injured in a spate of bomb attacks in the Iraqi capital, Baghdad, and two nearby towns.

The most deadly was caused by a car bomb in the mainly Shia Sadr City area.

The same district was hit by a massive truck bomb two days ago that killed more than 60 people and was claimed by Islamic State militants.

Sadr City has been the target of several bomb attacks this year claimed by IS who consider Shia to be heretics.
