Very Urgent: Massacre on Pearl Roundabout and Salmaniya Right Now / Photos - March 16th http://www.abna.ir/data.asp?lang=3&Id=231698

Four tanks and half a dozen other armored vehicles were positioned 300 yards from Pearl with soldiers manning machine guns, and helicopters circled the area but didn't immediately intervene. Dozens of soldiers milled about casually outside the square as smoke rose. More than 20 white buses stood nearby, apparently used to transport riot police.
