Farewell Gorbachev, Ukraine's nuclear plant, UN Xinjiang report, Pakistan floods

He changed the course of history. Mikhael Gorbachev passing away this week at 91. Thirty years after the last Soviet president left power, he is remembered in the West as an unlikely hero. We have images of then president Leonid Brezhnev pinning a medal on the then-chair of the Communist Party Standing Commission on Youth Affairs date back to 1979. Who knew that six years later, the unassuming apparatchik would rise to the rank of radical reformer.
