A video posted on YouTube in the last few hours has this description:

The FSA captures a missile storage base near Damascus. Some of the missiles were being modified by the Assad regime so that chemically charged warheads could be fixed on them.

I can’t confirm any of that information or say anything about the Arabic text at the beginning. What seems evident, nevertheless, is that this video was indeed made in a missile storage facility which is no longer under the control of the Syrian military.

Watch the video at YouTube — embedding has been disable so I can’t post the video here.
