Former mixed martial artist Shamil Abdulmuslimov has been shot dead by two gunmen wielding Kalashnikov-series rifles in the city of Khasavyurt in Dagestan after an argument allegedly over a plot of land.

Twenty-five-year-old Abdulmuslimov, who had a record of 11-4 under various promotions, was gunned down on Thursday following an alleged land dispute with a local father and son.

The killers, reported on Baza Telegram channel as Murgamudin Muradisov and his son, were said to have become embroiled in a heated exchange with the former fighter after which they left the establishment.

However, the elder Muradisov was then caught on camera arriving at the restaurant armed with a Saiga-12 semi-automatic rifle, part of the Kalashnikov series of rifles designed by Mikhail Kalashnikov, famed for designing the AK-47.

After crashing his car, Murgamudin can be seen storming into a corner of the restaurant where Abdulmuslimov was seated and opening fire on the unsuspecting former heavyweight, then proceeding to beat and shoot at members of his entourage with their rifles.
