Yevgeny Prigozhin says in a new video message that all military sites in the Russian city of Rostov-on-Don are under the Wagner mercenary group’s control, Reuters is reporting.

The Wagner chief also says in the video, which was posted to Telegram, that he and his men are in the southern district military headquarters in Rostov-on-Don.

Prigozhin appears to say on the video that his men will blockade Rostov-on-Don and head for Moscow unless Sergei Shoigu, the Russian defence minister, and Gen Valery Gerasimov come to them.
