A U.S. C-130 transport plane has crashed near Jalalabad, Afghanistan, according to military defense officials. Jalalabad, which is near the eastern border of Pakistan, is prone to Taliban attacks.

The early morning crash happened approximately 3:30 a.m. local time Friday, said coalition spokesperson U.S. Army Col. Brian Tribus, according to NBC News.

The United States Air Force operates out of the Jalalabad Airport, often using American drones, according to the Telegraph.

"Cause of the crash and status of crew and others onboard remains unknown," said Tribus. "We are gathering more information and will release as appropriate."

No word yet as to how many people were onboard, according to Sputnik News, or if there were any casualties.

The U.S. C-130 Hercules is a turboprop aircraft used to transport oversize cargo and military personnel, designed and built by Lockheed Martin. The C-130 has been an American military staple since the 1950s and is known to be a workhorse in the U.S. Air Force's Afghanistan operations.
