Syrian military forces are already moving chemical weapon stockpiles out of the country to evade looming UN inspections, an opposition leader said Saturday.

“We have told our friends that the regime has begun moving a part of its chemical weapons arsenal to Lebanon and Iraq,” Gen. Salim Idris, the top commander of the Free Syrian Army (FSA), told reporters in Istanbul.

“We told them do not be fooled,” he said, according to Reuters.

The FSA is the largest and most organized of the rebel factions battling to overthrow longtime Syrian President Bashar Assad’s forces in the country.
