Medvedev: More U.S. weapons supplies only trigger more retaliation from Russia

Former Russian President Dmitry Medvedev has said the supply of more advanced U.S. weaponry to Ukraine will only trigger more retaliatory strikes from Russia, up to the extent of Russia's nuclear doctrine.

"All of Ukraine that remains under Kyiv's rule will burn," journalist Nadana Fridrikhson quoted him as saying in a written interview with her.

Asked what would happen if the weapons that Washington has promised Ukraine were to strike Crimea or deep into Russia, Medvedev said, "We don't set ourselves any limits and, depending on the nature of the threats, we're ready to use all types of weapons. In accordance with our doctrinal documents, including the Fundamentals of Nuclear Deterrence."
