A deadly shootout between two Chechen clans took place in Moscow on Monday evening.

According to a report from Life.ru that was translated by Karim Zidan of Bloody Elbow, former UFC and Strikeforce fighter Adlan Amagov was allegedly involved in the violent incident where two were left dead and six people injured.

According to the report, Amagov was sided with the Khalidov clan, who fought against the Baysurov clan. Amagov allegedly stabbed 19-year-old MMA fighter Timur Baysurov in the chest during the fight. Baysurov was taken to a hospital intensive care unit and treated for his injuries. Guns were also involved in the fight between the two clans as two were killed and five other people were injured.

Reports suggest that the incident started as a business negotiation at Krylatsky Hills in Moscow, which turned violent after agreements could not be made. The business negotiation meeting was led by ‘Grand’ and ‘Three Pillars’ furniture centers owner, Magomed Khalidov and CEO of Intro Energy, Ruslan Baysurov.

Moscow police are still investigating the incident and have filed a criminal case for murder and illegal transfer of firearms.

Adlan Amagov holds a 13-2-1 professional MMA record and trained at Jackson Wink MMA. Amagov’s last professional MMA fight was at UFC 166 back in 2013. Amagov went 2-0 in the UFC after going 3-1 in Strikeforce and retired from the sport. Amagov’s single loss in Strikeforce was against former Strikeforce and UFC champion Robbie Lawler. Amagov’s only other loss was in his professional MMA debut back in 2007 at the Perm Regional MMA Federation: MMA Professional Cup where he lost to Aleksei Oleinik by an Ezekiel Choke submission. Amagov retired because he said he was tired of cutting weight for fights after some speculated it was due to religious reasons.

Since retiring from MMA, Amagov competed in a mixed-rules Sambo bout in 2016, beating Dirlei Broenstrup in the first round by armbar submission.
