PARIS (Reuters) - France will not review its 1.2 billion-euro (980 million pounds) contract to sell helicopter carriers to Russia earlier than planned because of the Ukraine crisis, despite U.S. concerns, a French government source said on Thursday.

Paris has come under pressure from Washington and some European partners to reconsider its supply of high-tech military hardware to Moscow, and has responded by saying it will review the deal in October - but not before.
