IS suicide bomber kills four at Iraq checkpoint

IS suicide bomber kills four at Iraq checkpoint: 

The bombing at a checkpoint leading to the Husseiniyah area, northeast of the capital, also wounded 21 people, the officials said.
IS issued a statement saying an Iraqi carried out a suicide bombing targeting a checkpoint, but gave the location of the attack as Shaab, an area adjoining Husseiniyah.
The blast is the latest in a series of deadly attacks in and around Baghdad, including a bombing in a crowded shopping district on July 3 that killed 292 people, one of the deadliest ever to hit Iraq.
