Deadly explosions in series of attacks on Iraqi cities
At least 38 people have been killed in a series of co-ordinated attacks across Iraq, officials say.
Two car bombs in the predominantly Shia city of Kerbala are reported to have killed at least 13 people.
Another car bomb near police headquarters in the northern city of Kirkuk killed seven people, according to hospital sources.
The attacks come ahead of next week's Arab League summit to be held in the capital, Baghdad.
