The Islamic State group has claimed responsibility for a wave of car bombs in mostly Shi'ite areas of Baghdad which killed at least 27 people on Saturday. The hardline Sunni Islamist organization which has led an offensive across **rthern and western Iraq said two of the explosions were suicide missions by bombers it named as Abu al-Qaaqaa al-Almaani and Abu Abdul Rahman al-Shami - **ms de guerre which suggested they were from Germany and Syria. Saturday's blasts were the deadliest in the Iraqi capital since the Sunni insurgency erupted in the **rthern city of Mosul and then swept through Sunni regions of Iraq towards Baghdad. The first suicide bombing took place at a checkpoint where soldiers, police and Shi'ite volunteer fighters were gathered, the Islamic State said in an Internet statement.
