The Soviet Union's last leader Mikhail Gorbachev warned Saturday that the world was on the "brink of a new Cold War" at an event to mark 25 years since the Berlin Wall's fall, the German news agency DPA reported.
"The world is on the brink of a new Cold War. Some are even saying that it has already begun," the 83-year-old said, amid tensions between the West and Russia over Ukraine.
