(Reuters) - Russia believes the risks of nuclear war should be kept to a minimum and that any armed conflict between nuclear powers should be prevented, the TASS news agency quoted a foreign ministry official as saying on Saturday.

       Vladimir Yermakov, the foreign ministry's head of nuclear non-proliferation, said all nuclear powers must stick to the logic laid out in official documents aimed at preventing nuclear war.

       "Russia clearly follows this understanding," Yermakov was quoted as saying.
