Moscow’s space chief has issued wild threats about deploying Russia’s "Satan-2” hypersonic missile after Vladimir Putin ’s foreign minister was blocked from travelling to Serbia.
Air space was closed by three NATO countries to prevent top diplomat Sergei Lavrov visiting Belgarde.
But the head of the Russian space agency Dmitry Rogozin hit back saying that while Bulgaria, Romania and Montenegro could stop his plane, they would not halt a 208-ton, 15,880mph Sarmat missile - a.k.a Satan-2.
