A Suicide attack in the Taji area, **rth of the Iraqi capital, killed at least seven people and wounded 17 on Thursday, security and medical officials said. It was **t immediately clear if the target was the area's sprawling military base or an entrance to Taji itself, and the number of Suicide bombers was unk**wn. US military trainers are based at Taji, helping to instruct some 1,600 Iraqi soldiers in a six-week programme aimed at readying them to face the Islamic State (IS) jihadist group. There was ** immediate claim for the attack, but Suicide bombings are a tactic almost exclusively employed by Sunni extremist groups in Iraq, including IS.
