CNN's Erin Burnett speaks to Fmr. spokesman for the U.S. state department, Jamie Rubin and Syria expert, Andrew Tabler about the crisis in Syria.
Secretary of State Hillary Clinton accused Russia of sending attack helicopters to Syria.
At a Washington think tank on Tuesday, Clinton said, "We are concerned about the latest information we have that there are attack helicopters on the way from Russia to Syria, which will escalate the conflict quite dramatically."
Clinton said the United States has repeatedly asked Russia to stop arms shipments to President Bashar al-Assad's regime, but Russia has said anything it is sending is not being used against the public unrest. "That's patently untrue," Clinton said before making the accusation about the helicopter shipments.
Clinton's comments were made at the Brookings Institution, where she was speaking alongside Israeli President Shimon Peres.
Intelligence officials refused to comment on Clinton's assertion. Washington's Russian embassy also would not comment.
