KABUL (Reuters) - The Taliban on Wednesday branded as fabricated the latest UN report on civilian casualties in Afghanistan that blamed insurgents for three-quarters of those killed and wounded in the first 10 months of 2010. In a quarterly report on Afghanistan this month, the United Nations said civilian casualties had risen by 20 percent between January 1 and October 31 this year compared with same period in 2009. Afghanistans Taliban, however, rejected the UN findings as at attempt to cover up US brutalities and described it as partial, one-sided and influenced by US politics. The Islamic Emirate considers the latest UN report as a self-fabricated figure and believes that this is also a propagandist effort for covering the American brutalities like the past 9 years in Afghanistan, the Taliban said in a statement emailed to media. It said the report would only mislead those who knew nothing about Afghanistan and would damage the UNs reputation. Insurgent suicide attacks and homemade bombs caused 998 deaths - 55 percent of the total attributed to the militants - and wounded 2,062 civilians - 70 percent of the total attributed to insurgents, the UN report found. Of the 742 civilian casualties attributed to pro-government forces, air strikes caused the largest number, including 162 deaths and 120 injuries, it said. Civilian casualties caused by US and other foreign forces have long been a source of friction between the Afghan government and its Western backers, and military commanders have sought to tighten engagement rules, including the use of air strikes. On Tuesday, NATO-led forces said they were investigating whether their troops had inadvertently killed five civilians after coming under attack in southern Helmand province. Violence across Afghanistan is at its worst since the Taliban were ousted by US-backed Afghan forces in late 2001, with military and civilian casualties at record levels despite the presence of about 150,000 foreign troops.
