The leader of the Wagner mercenary group, Yevgeniy Prigozhin, is expected to go to Belarus under a deal brokered by the Belarusian president, putting an end to a shocking, albeit short-lived, challenge to Russian President Vladimir Putin’s authority. Prigozhin will not be prosecuted, a Kremlin spokesman said, adding that Wagner forces who did not join what Putin called a “rebellion” would be absorbed into the Russian Defense Ministry.
