Twin roadside bombs in the Urr neighbourhood of north Baghdad killed at least 10 people and wounded at least 32 on Thursday evening, security officials said. A defence ministry official put the toll at 10 dead and 32 wounded, while an interior ministry official said 12 people were killed and 45 wounded in the blasts. They both spoke on condition of anonymity. The interior ministry official said that the first bomb exploded at around 7:00 pm (1600 GMT). Following a common pattern in Iraq attacks, a second bomb was set off after security forces and other people gathered at the scene. \"The first bomb was not that powerful, but the second was strong,\" said Wissam Nauhas, an eyewitness who said he was out buying bread for dinner. \"After the second explosion, policemen fired into the air and ambulances started to arrive.\" There were two police and two soldiers among the dead, and three police and two soldiers among the wounded, the interior ministry official added. Violence in Iraq is down markedly from its peak in 2006 and 2007 but attacks remain common. A total of 185 people were killed in violence in September, according to official figures.
