Other reports / speculation have the Israeli commandoes inside the buildings stealing stuff before the bombing raid. Would fit perfectly.

Syria: Russia Upgrades Air-Defense System
October 02, 2007 14 48 GMT
Russia has sent a team of technicians to Syria to upgrade the Syrian air-defense network, London daily The Times reported Oct. 2. The team reportedly was dispatched after Syrian airspace was penetrated by an alleged Israeli airstrike Sept. 6 near Dayr az-Zawr. The Times report also suggests that the Israeli air force successfully applied, for the first time, a sophisticated electronic warfare system that jammed Syria’s Russian-made radar during the attack.
