WASHINGTON (Reuters) – US intelligence agencies believe Syria’s government has
likely used chemical weapons on a small scale, the White House said on Thursday,
but added that President Barack Obama needed “credible and corroborated” facts
before acting on that assessment.
The disclosure of the assessment, which
Defense Secretary Chuck Hagel said was made within the past 24 hours and the
White House said was based in part on physiological samples, triggered immediate
calls for US action by members of Congress who advocate deeper US

statement that chemical weapons were used in Syria.
secretary’s admission came two days after Brig.-Gen. Itai Brun, head of Military
Intelligence’s Research Division, said, “We believe the regime has, and is
using, chemical weapons” – probably sarin – against rebels trying to overthrow
Assad, and that it has done so several times.
The Prime Minister’s Office
also refused to relate to those comments, apparently out of a desire to avoid a
conflict with the US administration over the matter. Obama has said that Assad’s
use of chemical weapons would constitute a “red line” that would trigger an

weapons would be a gamechanger, his administration made clear it would move
carefully – mindful of the lessons of the start of the Iraq War 10 years
Then, the George W. Bush administration used faulty intelligence to
justify the Iraq invasion in pursuit of nuclear, chemical and biological weapons
that turned out not to exist.
“Given the stakes involved, and what we
have learned from our own recent experiences, intelligence assessmentscredible and corroborated facts that provide us with some degree of certainty
will guide our decision-making,” Miguel Rodriguez, White House director of the
office of legislative affairs, said in a letter to lawmakers.
US defense official told reporters that “we have seen very bad movies before”
where intelligence was perceived to have driven policy decisions that later, in
the cold light of day, were proven wrong.
The White House said the US
intelligence community assessed with varying degrees of confidence that the
chemical agent sarin was used by the Syrian government. But it noted that “the
chain of custody is not clear.”
“So we cannot confirm how the exposure
occurred and under what conditions,” according to the White House letter, sent
The term “varying degrees of confidence” also usually
suggested debate within the intelligence community about the assessment, the
defense official noted.
The scale of the sarin use appeared limited, with
one US intelligence official noting that nobody was “seeing any mass casualties”
from any Syrian chemical weapons use.

advocates of deeper US involvement in Syria’s civil war, said the US
intelligence assessment demanded Washington follow with action.

Corker of Tennessee, the top Republican on the Senate Foreign Relations
Committee, said there was likely still a need to check on chemical weapons
“There realistically is probably some additional steps that need to
be taken to verify, but... there are indications a red line has been crossed,”
Corker told reporters.
Syria’s deputy foreign minister, Faisal Mekdad,
told Reuters that US aid to the rebels may backfire and lead to attacks on
American soil like those of September 11, 2001.
“Once the fire of
terrorism spreads in Syria it will go everywhere in the world,” he said in an
interview in Damascus.
The White House has not specified what action
Obama might take if he determines with certainty that Syria has used chemical
weapons. But in its letter to lawmakers, it said it was “prepared for all
