Kabul, Afghanistan (CNN) -- At least six American service members died in a "gunfight" Wednesday at an airport in the Afghan capital, an Afghan military official told CNN.
"A 50-year-old man opened fire at armed U.S. military soldiers inside the airport after an argument between them turned serious," said Col. Baha Dur, chief of the public relations for the Afghan National Army at Kabul military airport.
The Afghan Defense Ministry said the incident, which occurred inside the Afghan national army base, stems from an argument between an Afghan pilot and an international colleague.
