:: The Central Intelligence Agency (CIA) is shutting down its program to support rebels fighting against Syrian President Bashar al-Assad, the Washington Post reported Wednesday.

Citing unnamed US officials, the Post said the four-year-old covert operation has had limited impact, especially since Russian forces stepped in to support Assad in 2015.

President Donald Trump made the decision to drop the program nearly a month ago, according to the Post, after meeting with CIA chief Mike Pompeo and National Security Advisor HR McMaster. White House and CIA officials declined to comment on the report.

The Post said phasing out the CIA program reflects Trump’s “interest in finding ways to work with Russia” as well as “an acknowledgment of Washington’s limited leverage and desire to remove Assad from power.”

The ceasefire

The decision came as the US and Russia negotiated a ceasefire in southwest Syria, covering some of the area from which the rebels operated. The ceasefire was announced on July 7 at the G20 Summit in Hamburg, Germany where Trump and Russian President Vladimir Putin held their first face-to-face meeting.

President Barack Obama approved the rebel aid program in 2013 as various insurgent groups sought external support in a general uprising against the Assad regime. Thousands of Syrian anti-government fighters were trained and armed.

But the US commitment remained ambiguous amid doubts in some quarters that the rebels could actually manage to depose Assad and as attention turned to the rising power of ISIS in Syria and Iraq.

Support for the program further eroded last year after the rebels lost the areas they held in the Syrian city of Aleppo under a brutal Russian-backed government assault.
