In retaliation for the execution of 47 prisoners, including the popular Shi’ite cleric Namr al-Namr, by Saudi Arabia, rioters in Iran stormed the Saudi embassy in Tehran.
The mob smashed the contents of the building and threw Molotov cocktails at the building.
So who believes the "mob" was doing anything but following government orders?
Why anybody keeps an embassy in Tehran is beyond me.
