A man claiming to be a Russian military commander defects to Norway

A man who claims to be a commander from the Wagner Group, a Russian mercenary group fighting in Ukraine, has fled to Norway. He told a Russian human rights activist that he was shot at and chased by dogs during his escape. He says he is prepared to testify against the Wagner Group’s founder and leader, Yevgeny Prigozhin, about extrajudicial executions committed by members of the mercenary group. The World’s Marco Werman speaks with Pierre Vaux, an expert on the Wagner Group, about the significance of the man’s defection and the mercenary group’s role in Russian military and foreign policy.
