US Defense Secretary Jim Mattis told Congress on Thursday that the US military does not have evidence that either chlorine or sarin were used in an alleged chemical attack in the Syrian town of Douma, adding that the Pentagon's only proof that such an incident occurred has come from social media and media reports.
"There have been a number of these attacks. In many cases, you know we don't have troops, we're not engaged on the ground there, so I cannot tell you that we had evidence, even though we had a lot of media and social media indicators that either chlorine or sarin were used," Mattis said when asked about the alleged attack in the Syrian town of Douma.
"I believe there was a chemical attack and we are looking for the actual evidence," Mattis said.
He added Washington was "committed to ending that war through the Geneva process through the UN orchestrated effort."
