KABUL, Afghanistan -- Officials in Afghanistan say a man in an Afghan army uniform turned his weapon on American trainers working with him in the country's east today, killing three of them.
The provincial governor's office says the gunfire erupted during argument between the Afghan soldier and his trainers. It says the soldier was also killed in the exchange and three other foreign trainers were wounded.
The international coalition says two American service members and one U.S. civilian died. It says a second Afghan man was arrested after the shooting and an investigation into the incident is underway.
So far this year, there have been five insider attacks on foreign forces, with a total of eight troops and one U.S. contractor killed. However, the number of such attacks has eased compared with last year.
Meanwhile, in the western province of Farah, an Italian soldier was killed and three others wounded in a grenade attack. The Taliban quickly took responsibility, claiming that the attacker was an 11-year-old boy. The provincial government disputes that, saying an adult man was seen throwing a grenade, then escaping by blending into the crowd at a nearby vegetable market.
