Defense Secretary Leon Panetta says intelligence suggests the Syrian government has moved some of its chemical weapons, but the U.S. believes that the main sites still remain secure.
Panetta says he does not have enough information to confirm if any of the moves suggest that some of the material has been acquired by the opposition forces battling the regime of Syrian President Bashar Assad.
It is widely believed that Syria possesses extensive chemical and biological weapons stockpiles and it has threated to use them if the country comes under attack. President Barack Obama has said there would be enormous consequences if the U.S. sees any movement or use of the weapons.
Panetta was speaking at a news conference with Canadian Minister of National Defense Peter MacKay.
