U.S. intelligence has determined “with varying degrees of confidence” that Syrian President Bashar al-Assad has used chemical weapons against his own people, pressing the two-year-old civil war up against the “red line” previously established by President Obama.
“Our intelligence community does assess with varying degrees of confidence that the Syrian regime has used chemical weapons on a small scale in Syria, specifically the chemical agent sarin,” the White House wrote in a letter to members of Congress Thursday.
Obama has said that the use of chemical weapons in Syria would cross a “red line” and prompt unspecified U.S. action. What Thursday’s news could mean in terms of U.S. involvement is not yet known. The bloody Syrian conflict is estimated to have caused more than 70,000 deaths–and created a growing refugee crisis.
Earlier this week, Israeli officials said they believed chemical weapons had been used against the opposition in Syria, following similar assessments by the French and British.
Defense Secretary Chuck Hagel shared the same information with reporters while traveling in Abu Dhabi Thursday. He stressed that U.S. officials are continuing to assess and gather information on the use of the weapons.
“We cannot confirm the origin of these weapons, but we do believe that any use of chemical weapons in Syria would very likely have been originated with the Assad regime,” Hagel said. Hagel did not say whether the use of chemical weapons crossed the president’s “red line.”
“As to a red line, my role as Secretary of Defense is to give the president options on a policy issue, that’s a policy issue,” he said. “And we’ll be prepared to do that as the president requires options.”
The White House is pressing for a “comprehensive United Nations investigation that can credibly evaluate the evidence and establish what took place” in Syria and is seeking “credible and corroborated facts” before taking action, according to a White House official.
“It’s precisely because we take this red line so seriously that we believe there is an obligation to fully investigate any and all evidence of chemical weapons use within Syria,” the official said.
But in a statement Thursday evening, a spokesperson for the United Nations Secretary-General said that the U.N. “is not in a position to comment” on intelligence from one nation.
