All 27 people on board a Kazakh military jet that crashed while carrying country's top border guard personnel have died, the Central Asian state's security service said Wednesday.

"All 27 occupants of the aircraft, including seven crew members, perished," the Nantional Security Service (KNB) said in a statement.

The victims included the acting head of the Kazakh federal border service Turganbek Stambekov and his wife, the statement said.

The plane crashed about 20 kilometres (12 miles) from Shymkent airport where it had been due to land after a flight from the capital Astana.

Kazakhstan's KTK television said the plane fell from a height of 800 meters (2,600 feet).

Footage of the crash site aired on Kazakh state television on Wednesday showed only fragments of the military transport plane remaining on the ground.

Khabar state television also cited local witnesses as saying that a heavy winter storm had descended the region at the time of the crash.
