The United States and countries near Syria are analyzing intelligence reports that the Syrian regime may have moved some of its chemical weapons inventories in recent weeks, a senior U.S. official told CNN.

The movement could be to consolidate storage because of deteriorating security in the country, the official said. Over the last 10 days, the United States has been trying to ascertain the legitimacy of the reports but has been unable to make any firm conclusions, officials from multiple U.S. government agencies said. None of the officials would agree to be identified because of the sensitive nature of the information.

U.S. officials say they don't know the extent of the movement, whether it's for consolidation or if it signals a move by the regime to potentially use such weapons. They says the U.S. wants to have multiple sources confirm the details before the intelligence analysts come to a firm conclusion.
