This is reported tonight, after the BBC report: Iraqi city cleared after clashes
With the “Green Zone” government policy to blackout the events of Karbala and to blur the magnitude of the disaster taking place in the city, Almelaf reported that Eyewitnesses say that the elements of the “Mahdi Army” [] engaged in the fighting in the city of Karbala are not citizens of the city, and that they arrived from other provinces [later reported that Sadr followers are calming the people saying that they are not involved in the fight].
Also, Almelaf said earlier that they are members of “Mahdi Army” [if they are!!!] using American weapons.
non14 confirmed the report saying:
Karbala shrines surrounded by unidentified gunmen
The group has targeted service facilities surrounding the holy shrine burning number of cars, Shrine officials say: “the group might demolish the shrine”.
Even American propaganda Radiosawa says:
It is not clear yet who is behind the clashes
