Russian Foreign Minister Sergei Lavrov said, responding to a question from Interfax as to whether Crimea can be regarded as a location to place Russian nuclear weapons: "Crimea has now become part of a country that has such weapons under the Treaty on the Non-Proliferation of Nuclear Weapons."
"And by international law, the Russian state has all grounds to dispose of its legitimate nuclear arsenal in accordance with its interests and in accordance with its international legal obligations," Lavrov said.
