Up to 15 people were killed and 36 wounded in bombings and shootings in Iraq on Sunday, police said. Two people were killed and seven wounded in a car bomb explosion near a Shiite religious school in al-Amin district in the eastern part of the capital Baghdad, an Interior Ministry source told Xinhua on condition of anonymity. In a separate incident, a roadside bomb ripped through Naheawan area in southeastern Baghdad, killing two people and wounding three others, the source said. Meanwhile, a civilian was killed and five wounded in another roadside bomb blast in Shurta al-Rabia district in the southwestern part of Baghdad, the source added. Earlier, police said that 10 people, including five soldiers, were killed and 21 wounded in separate attacks in northern and central Iraq. Iraq is witnessing its worst eruption of violence in recent years, which raises fears that the country is sliding back to the full-blown civil conflict that peaked in 2006 and 2007, when monthly death toll sometimes exceeded 3,000. The UN Assistance Mission for Iraq recently reported that over 1,000 Iraqis were killed and more than 2,300 wounded in acts of terrorism and violence in July, the deadliest month in more than five years.
