A car bomb targeting security forces killed four Iraqi primary school pupils and wounded two others on Monday, security and medical officials said. The vehicle was parked near a school in the town of Heet, 160 kilometres (100 miles) west of Baghdad. It exploded at around 8:00 am (0500 GMT) as the children were arriving for classes and as a security forces anti-terrorism unit passed by, the officials said. Colonel Ayada al-Nimrawi, deputy police chief in Heet, said the blast killed four children and wounded another two. Dr Subhi Abed al-Alwani confirmed the toll. They said members of the security patrol were unscathed. Violence in Iraq has decreased since its peak in 2006 and 2007, but deadly attacks still occur almost every day. With the latest violence, at least 179 people have been killed and 676 wounded in attacks in Iraq so far this month, according to an AFP tally based on security and medical sources.
