The 66 U.S. service members killed this month eclipses the 65 killed in July 2010, according to an Associated Press tally. Nearly half the August deaths occurred when insurgents shot down a Chinook helicopter Aug. 6, killing 30 American troops, mostly elite Navy SEALs.
Violence is being reported across Afghanistan despite the U.S.-led coalition's drive to rout insurgents from their strongholds in the south.
Though American military officials predicted high casualties this summer as the Taliban try to come back after recent offensives, the grim milestone increases pressure on the Obama administration to withdraw U.S. forces quickly.
The military has begun to implement President Barack Obama's order to withdraw the 33,000 extra troops he dispatched to the war. He ordered 10,000 out this year and another 23,000 by summer of 2012, leaving about 68,000 U.S. troops on the ground. Two National Guard regiments comprising about 1,000 soldiers started going home last month.
Aside from the 30 Americans killed in the Chinook crash southwest of Kabul, 23 died this month in Kandahar and Helmand provinces in southern Afghanistan, the main focus of Afghan and U.S.-led coalition forces. The remaining 13 were killed in eastern Afghanistan. -- AP
