Thirteen children killed at school amid wave of bombings Target: An Iraqi child, wounded in the school attack, receives medical care at a hospital in the northern Iraqi city of Dohuk. A suicide bomber detonated a truck filled with explosives on the playground of a primary school in northern Iraq, killing 13 children and the headmaster, police said. Shortly afterwards, another suicide bomber in a truck struck a police station in the same village, killing three officers. The two attacks in Qabak, a Shiite Turkmen village just outside Tal Afar in Mosul province, also left 95 people wounded, 80 of them at the school. The attacks added to a wave of violence across the country, the deadliest outbreak in Iraq since 2008. A suicide bomber attacked a group of Shiite pilgrims in Baghdad on Sunday, police said, killing 14 and wounding 34 and raising the total death toll from terrorist attacks on Sunday to at least 31. Abdul Aal al-Obaidi, the mayor of Qabak, called the attack on the school "a crime against humanity" as he surveyed books splattered with blood. "The terrorists are trying to stop us from living and sending our children to school, but they will not, as we have our unity," he said. Many children were seriously wounded and were sent to larger, better-equipped hospitals in the Kurdistan region of Iraq for treatment, medical officials said. "I don't remember what happened," said a sobbing boy named Ali, who suffered wounds to his face and legs. I just want to see my mother. In Baghdad, Shiite pilgrims visiting the shrines of revered imams were hit for the second time in less than 24 hours despite heightened security measures. One wounded pilgrim, Abdul Amir, speaking from a Baghdad hospital, remained defiant. "They killed more than 50 of us yesterday, and they thought that we would stop," he said. They thought wrong. We will never stop visiting our imams. Our security forces just look at us and do nothing. Violence worsened after security forces stormed a Sunni Arab anti-government protest camp in northern Iraq on April 23, sparking clashes in which dozens died. The authorities have made some concessions aimed at placating anti-government protesters and Sunnis in general, such as freeing prisoners and raising the salaries of those Sunnis fighting against al-Qaeda, but underlying issues remain. While security forces have struck against militants, they have yet to succeed in curbing theattacks. New York Times, AFP
