I'll make just one very small remark: both sides have been willing to meet with the UN special envoy—both Mr. Annan and Mr. Brahimi—but what they aren't willing to do is negotiate with the other side, either directly or through him. But they are willing to meet with him. I just wanted to make that absolutely clear.
Yes, the regime is being resupplied. It is being resupplied, to the best of our knowledge, by Russia and Iran. Indeed, you're absolutely right that the Turks recently intercepted a Syrian Arab Airlines civilian aircraft overflying Turkey on its way back to Damascus from Moscow. They had information that led them to believe this aircraft was carrying equipment or weapons related to the war effort.
When they inspected the aircraft, they did indeed find such material, which they proceeded to unload and impound.
