Civilian deaths rose in August to their second-highest monthly level this year, according to figures compiled Saturday by The Associated Press. At least 81 American service members also died in Iraq during August — an increase of two over the previous month but well below the year's monthly high of 126 in May. American deaths surpassed the 80 mark during only two months of 2006. Figures compiled by the AP from police reports nationwide show that at least 1,809 civilians were killed across the country last month compared with 1,760 in July. That brings to 27,564 the number of Iraqi civilians killed since AP began collecting data on April 28, 2005. According to the AP count, civilian deaths reached a high point during the wave of sectarian bombings, kidnappings and killings at the end of last year — 2,172 in December and 1,967 in the previous month.
