RT - Moscow considers recent statements by the US ambassador to London on the Iran nuclear deal �mistaken and inappropriate,� Russian Foreign Ministry spokeswoman Maria Zakharova said on Wednesday.

Britain should side with the US rather than Brussels over Iran, Ambassador Robert Wood Johnson said, calling on America�s �closest ally� to reverse its position on the controversial nuclear deal. Writing for The Telegraph, Johnson challenged the UK �to abandon its European neighbors who are still backing a deal to trade with Iran and join forces with America to enforce hard-hitting sanctions,� the newspaper said.

According to Zakharova, it is not Tehran that destabilizes the region, �but rather those who too loosely treat international agreements, especially in such areas as nuclear security.� She added that the US is trying to �destabilize the situation inside Iran through illegal economic sanctions and through political pressure,� RIA Novosti reported.
