Series of bombings kill 19 in Iraq A suicide attacker and a car bombing have killed at least 19 people in separate attacks in Iraq. A SUICIDE attacker and a car bombing have killed at least 19 people and wounded 38 in separate attacks targeting Shi'ites north of Baghdad. There was no immediate claim of responsibility for Friday's attacks, the latest in an increasing wave of violence across the country. Iraq has been facing its deadliest outburst of violence since 2008, with more than 2000 people killed since the start of April. The bloodshed appears to be largely the work of resurgent Sunni militants such as al-Qaeda's Iraq branch, feeding off Sunni discontent with the Shi'ite-led government. The deadliest attack on Friday took place in Baghdad's Kiraiyat neighbourhood as worshippers gathered after the evening call to prayers at the Hussienieh Ali Basha mosque. A suicide bomber walked in during the service and detonated his explosives, killing 15 worshippers and wounding 32, a police officer and a medical official said. Earlier an explosives-laden vehicle detonated near a Shi'ite protest camp in the city of Samarra, a police officer said. The head of the Salahuddin provincial health directorate, Raed Ibrahim, later confirmed the casualty figures in the attack in Samarra, 95km north of Baghdad. Since December, Iraq's Sunni minority has been staging demonstrations over what it calls second-class treatment by the Shi'ite-led government. In some place clashes have erupted between security forces and protesters. Violence increased sharply in April and May, with frequent bombings in civilian areas raising concerns that a widespread sectarian conflict could once again break out in Iraq. The bloodshed accelerated after a deadly April 23 crackdown by security forces on a Sunni anti-government protest in the northern town of Hawija in which 23 people were killed. Hoping to stem the violence with a sign of solidarity, both Sunni and Shi'ite worshippers gathered on Friday at Abdul-Qadir al-Gailani Mosque in downtown Baghdad to kneel and pray side by side. As they prayed, the mosque remained under tight security.
