A fast-moving crisis unfolded in Russia on Saturday as Vladimir Putin faced an apparent insurrection from a former ally, Yevgeniy Prigozhin, and the Russian mercenary fighters he leads.

For the moment, things appear to be calming down, as the forces answering to Prigozhin, the Wagner Group chief, have halted their march toward Moscow and turned around. The development came after an agreement between Prigozhin and Putin was brokered by Belarusian President Alexander Lukashenko, according to Kremlin spokesperson Dmitry Peskov. Criminal charges previously started against Prigozhin will be dropped, and the Wagner boss will go to Belarus, Peskov said.
