Nuclear non-proliferation at risk: Ukraine PM

Ukraine's interim Prime Minister Arseniy Yatsenyuk told the UN Security Council on Thursday that nuclear non-proliferation was at risk unless his country and Russia could resolve their crisis.

Yatsenyuk said that, unless Russia agrees to a real dialogue, the crisis could undermine global security and nuclear non-proliferation.

"As after these actions it would be very difficult to convince anyone in the globe not to have nuclear weapons," he said.
