Hijjah, 1431/Nov. 23, 2010, SPA -- Violence in Afghanistan hit an all-time high in recent months and the insurgency is growing more sophisticated, Reuters quoted the U.S. military as saying on Tuesday. In a periodic report to Congress, the Pentagon said that all types of violent incidents in Afghanistan had increased from April through the end of September -- up 300 percent from 2007 -- except for the use of roadside bombs. While the military noted that insurgents' geographic reach and sophistication had grown, it also said security was slowly spreading across the country.
