Russia has warned the US of ‘severe repercussions’ on ties between the two countries if the recently tightened sanctions on Iran affect Russian businesses in the country.
"We assume that (Russian) companies which do violate the restrictions imposed by the UN Security Council (on Iran) will not be affected by the anti-Iranian American laws," the Russian Foreign Ministry said.
The US imposed fresh sanctions on Teheran last week, including making it mandatory for US firms to declare any business with Iran.
