News of the defection was first reported on the pro-Assad website Syria Steps, which said he made an “escape,” calling his leave “insignificant,” according to the BBC.
"Even those close to Assad have begun to understand that one cannot support a slaughterer like Bashar al-Assad," Fabius said.
The defection comes as Secretary of State Hillary Clinton is in Paris for the “Friends of Syria” conference, the latest in a series of meetings between nations hoping to find a solution to the crisis in Syria.
Russia and China, who have blocked further United Nations action in Syria, did not attend the meeting.
