Violence in Iraq caused the deaths of more than 15,000 civilians and security personnel in 2014, government figures show, making it one of the deadliest years since the 2003 US-led invasion. Last year's toll of 15,538 was more than double the 6,522 people killed in 2013. It was the worst in seven years, the Iraqi government said, almost reaching the toll of 17,956 during the height of 'Sunni-Shiite' sectarian killings in 2007. The UN put the number of civilians killed in Iraq during 2014 at 12,282.
