BEIRUT -- A high-ranking member of Iran's Revolutionary Guard Corps was assassinated this week while traveling from Syria to neighboring Lebanon, Iranian media reported Thursday, in the strongest indication to date that senior Iranian military commanders have been dispatched to Syria. Gen. Hassan Shateri was killed Tuesday by "unknown gunmen," described as "suspected Israeli agents," as he was on the road between the Syrian capital of Damascus and Beirut, the capital of Lebanon, various Iranian news agencies reported.
