The Taliban quickly claimed responsibility for downing the Boeing 747-400, but NATO said in a statement to The Associated Press that the Taliban "claims are false." The coalition says the cause of the crash was being investigated by emergency crews that rushed to the site, but there was no sign of insurgent activity in the area at the time.
Capt. Luca Carniel, a coalition spokesman, said the aircraft crashed from a low altitude right after takeoff.
The plane -- owned by National Airlines, an Orlando, Florida-based subsidiary of National Air Cargo -- was carrying vehicles and other cargo, according to National Air Cargo Vice President Shirley Kaufman. She said those killed were four pilots, two mechanics and a load master, who was responsible for making sure that the weight and balance of the cargo is appropriate.
Five of the seven fatalities were from Michigan, said Kaufman.
"We are not yet releasing the identities of the colleagues we lost out of respect for their families who need a little more time to reach other loved ones," she said in an email to the AP.
The U.S. National Transportation Safety Board and the Afghanistan Civil Aviation Authority are investigating the crash, she said.
