After years of telling the public that the United States has about 900 troops in Syria, the Pentagon has revealed there are approximately 2,000 soldiers there — double the previous estimate.

Speaking to reporters on Thursday, Pentagon spokesperson Pat Ryder said the additional US forces have been in Syria since before the ouster of former President Bashar al-Assad this month, though he did not specify a timeframe.

“We have been briefing you regularly that there are approximately 900 US troops deployed to Syria. In light of the situation in Syria and the significant interest, we recently learned that those numbers were higher,” Ryder said.
