PM fires Baghdad's top security officials in order to relieve public anger

Islamic State group extremists attacked a Shiite shrine north of Baghdad, killing 37 people, just days after one of the deadliest bombings in the country, officials said on Friday.

The overnight attack on the Sayyid Mohammed shrine in Balad, which involved suicide bombers and gun and mortar fire, also wounded 70 people.
