KABUL, Afghanistan (AP) — The U.S. military trainers handed the new recruit, Mohammad Ismail, his AK-47 to defend his remote Afghan village. He turned around and immediately used it, spraying the Americans with bullets and killing two — the latest of nine U.S. service personnel gunned down in two weeks by their supposed Afghan allies.

The shooting in western Farah province was not the only such attack Friday. Hours later a few provinces away in Kandahar, an Afghan soldier wounded two more coalition servicemen.
