Baghdad - A civilian cargo plane carrying six crew members and one passenger crashed in western Iraq on Thursday, a US military spokesman said.
According to the CNN website, either a mechanical failure or a pilot error appeared to have caused the accident.
Despite affirming that there was no high-profile coalition personnel on board, the spokesman said the status of the crew members was not yet known.
It was reported earlier on Thursday that an airplane made an emergency landing in Anbar province, south of the city of Fallujah, a bastion of Iraqi militants.
