Russia says no reason not to supply S-300 missiles to Assad

U.S. military strikes on Syria last week removed any moral obligation Russia had to withhold S-300 anti-aircraft missile systems from its ally Syrian President Bashar al-Assad, Russian Foreign Minister Sergei Lavrov said on Friday, according to RIA state news agency. Lavrov was also quoted as saying that, prior to the U.S. strikes on Syrian targets, Russia had told U.S. officials which areas of Syria represented "red lines" for Moscow, and the U.S. military action did not cross those lines.
