UN chief Ban Ki-moon has told Vladimir Putin that he’s “deeply concerned” about the crisis between Russia and Ukraine.
Ban met Putin in Moscow, as the country’s lower house of parliament voted to approve a treaty to absorb the Ukrainian region of Crimea into Russia.
“I was profoundly concerned by the recent incident where Ukrainian military bases were taken over,” said Ban.
“It is at moments like this in history that a small incident can quickly lead to a situation spiralling out of anyone’s control.”
Earlier on Thursday, the UN chief met Russian Foreign Minister Sergei Lavrov.
Ban is expected to travel to Kyiv on Friday on a visit which the UN says is “part of (his) diplomatic efforts to encourage all parties to resolve the current crisis peacefully.”
