A process, which is probably to bring down the regime, began in three and a half months ago. The process is characterized by increasing popular demonstrations. It has been responded by a harsh crackdown from the government and has so far claimed the lives of 1500 civilians, largely unarmed, whose only "sin" had been their desire to see the government replaced as well as have their rights respected and their urgent needs met by the state. In contrast to the previous round in 1982, which ended up with a massacre in amid a media blackout, the current struggle has soon found its way into the media with scenes of atrocities of slain, wounded and tortured people shocking anyone who has a little bit of conscience. The brutality and cruelty of the security forces have unleashed a sectarian tension which had been contained for decades.
