Russia said Friday it had "irrefutable" evidence that the deadly Syria chemical weapons attack that has prompted the U.S. to consider airstrikes was fabricated. Foreign Minister Sergey Lavrov told a news conference that there was a "very alarming atmosphere" over the issue and likened plans for a military response to failed action in Libya. "God forbid any other military gambles will be taken in Syria," he said. Lavrov cited "irrefutable data that [this] was yet another staged event and staging was done ... by the special services of one of the countries at the forefront of the anti-Russia campaign."
