After being told that death was the punishment for further disruption, Mousavi and thousands of protesters came back for more, clashing with riot police and the Basij. There are sporadic reports of capsicum (pepper spray) being dumped from helicopters to break up the crowd, reports of gunfire, and numbers of violent clashes that have apparently left hundreds of riot police injured. Busses, cars, motorcycles, mosques, and the Ahmedinejad supporters' Headquarters have all been set on fire. The Shrine of Khomeini has been bombed by a suicide bomber,
Sporadic clashes continue, though the police seem to have managed to break up much of it without actually killing protesters--excellent execution on their part.
But it is highly unclear that the regime has ended the protests, or seriously slowed them down. @BreakingNews on Twitter had the following:
"BULLETIN -- IRANIAN OPPOSITION LEADER MOUSAVI SAYS HE IS "READY FOR MARTYRDOM" AND WILL CONTINUE HIS PATH."
There is almost certainly a hardcore group of protesters ready to follow him to the end (see last post). They will continue to make life incredibly difficult for the regime until they are rounded up.
