Between the wounded people there were a German brigadier general, two Afghan generals and another Afghan officer. The assailant was subsequently killed. NATO said it was investigating the attack, considered an “insider terrorist attack.” It is “an act by the enemies who don’t want to see Afghanistan have strong institutions,” the Afghan President Hamid Karzai said in a statement. Such attacks are sometimes claimed by the Taliban insurgency. The targed of the violence is a large spectrum now in Afghanistan, including not only military presences but at the same time foreign aid workers, contractors, journalists and other civilians. The civilian death toll in the war in Afghanistan rose 17 percent for the first half of this year. On the same day, Tuesday, a police car struck a roadside bomb in the eastern province of Nouristan, killing three officers.
