PRAGUE - U.S. Secretary of State Hillary Rodham Clinton says Syrian action on chemical weapons remains a "red line" for the Obama administration and that it would prompt action from the United States.
Speaking in Prague, Clinton didn't address news reports of fresh activity at Syrian chemical weapons depots.
But she stressed Monday that Washington would address any threat that arises.
Syria is believed to have several hundred ballistic surface-to-surface missiles capable of carrying chemical warheads.
Its arsenal is a particular threat to American allies Turkey and Israel.
President Barack Obama declared the Assad regime's deployment or use of chemical weapons a "red line" for U.S. intervention in the Syrian civil war earlier this year.
