Gorbachev says world is on brink of new Cold War

BERLIN (Reuters) - Former Soviet leader Mikhail Gorbachev warned in a speech in Berlin on Saturday that East-West tensions over the Ukraine crisis were threatening to push the world into a new Cold War, 25 years after the fall of the Berlin Wall.

Gorbachev, who is credited with forging a rapprochement with the West that led to the demise of communist regimes across Eastern Europe, accused the West, and the United States in particular, of not fulfilling their promises after 1989.
