"Syrian national party offices on fire"

and

"Hezbollah leader Hassan Nasrallah, speaking on his party's Al Manar TV, urged against the demonstrations and called for an end to the violence."

"Earlier in the day, pro-Syrian Lebanese President Emile Lahoud and parliament speaker Nabih Berri, leader of the Shia Amal Party, also called for calm in the capital."

I don't see how you can blame this on Hezbollah or the U.N.

Who do you think might want to stir up trouble in Lebanon?
