At Least 6 Americans Killed in Afghan Gunfight

According to CNN:

Afghan officials have reported that a gunfight broke out in an airport in the Afghan capital of Kabul, killing at least six American service members. Col. Baha Dur announced that, "A 50-year-old man opened fire at armed U.S. military inside the airport after an argument between them turned serious."
