Dmitry Medvedev, now Russian security council deputy chairman, sent the warning after America agreed to provide Ukraine with advanced rocket systems that can strike with precision at long-range Russian targets.
Medvedev told Al Jazeera: "If, God forbid, these weapons are used against Russian territory then our armed forces will have no other choice but to strike decision-making centres.
