80 years ago, on 23 - 24 February 1944, Soviet security forces moved into areas of the North Caucasus and loaded hundreds of thousands of Chechen and Ingush people onto lorries and then cattle trucks, to Central Asia and Siberia.
It's estimated that 170,000 to 200,000 of the Chechens alone lost their lives. That's over a third of the total Chechen population. The survivors only started returning to their homeland after the death of Stalin in 1953.
