Yevgeny Prigozhin, the leader of the Wagner Group, claims his fighters crossed the Ukraine-Russia border into Rostov-on-Don.

Prigozhin threatens to destroy anyone who opposes his forces.

Tension between the Wagner Group and the Russian military has been escalating.

Prigozhin accuses the Russian military of launching a deadly missile strike on his troops without evidence.

Authorities deny the strike and deem Prigozhin's actions illegal.
