Syria’s Ikhbariyah TV on Thursday showed pictures of a truck full of weapons and reported that it was captured by the Syrian army.
The weapons included Israeli rockets and pictures were shown of weaponry, military jackets and binoculars.
The truck was reportedly headed to Sbeineh in southern Damascus, when the Syrian army captured it and seized the weapons on board.
At least 70,000 people have been killed in the two-year-old revolt against Syrian President Bashar al-Assad and the violence has stoked tensions across the Middle East.
France and Britain have stepped up calls to lift the arms embargo to permit supplies to the Syrian opposition to level the playing field in the conflict.
But other EU governments, including Germany, have resisted the move, fearing it will fuel violence in the region.
Britain and France hope the threat of arming the rebels will force Assad into talks and a transition of power.
