From a Washington Post obit by David E. Hoffman headlined “Mikhail Gorbachev, last leader of the Soviet Union, dies at 91”:

Mikhail S. Gorbachev, the last leader of the Soviet Union, who embarked on a path of radical reform that brought about the end of the Cold War, reversed the direction of the nuclear arms race and relaxed Communist Party controls in hopes of rescuing the faltering Soviet state but instead propelled it toward collapse, died Aug. 30 in Moscow.

His death was announced by Russian news agencies, citing the government hospital where he was being treated.
