French media quoted an anonymous official as saying that Russia promised to freeze the delivery of the S-300 surface-to-air missiles.

Russia would have to take responsibility for the breach of the contract, according to the same source.

Sarkozy praised Russia's decision as an "extremely courageous measure."

The two leaders had a working lunch at the Elysee Palace, but Putin left without speaking to reporters.

The U.N. Security Council on Wednesday approved a fourth round of sanctions against Iran over suspicions its nuclear program is aimed at developing weapons.

The S-300 air defense system is an advanced mobile system that can shoot down aircraft and cruise missiles from up to 150 km away. The United States and Israel oppose the sale of the missiles to Iran.
