DUBAI, United Arab Emirates (AP) Iranian security forces fired both live ammunition and tear gas to disperse demonstrators protesting against the Islamic Republics initial denial that it shot down a Ukrainian jetliner, online videos purported to show Monday.

Videos sent to the New York-based Center for Human Rights in Iran and later verified by The Associated Press show a crowd of demonstrators near Azadi, or Freedom, Square fleeing as a tear gas canister landed among them. People cough and sputter while trying to escape the fumes, with one woman calling out in Farsi: They fired tear gas at people! Azadi Square. Death to the dictator!

Another video shows a woman being carried away in the aftermath as a blood trail can be seen on the ground. Those around her cry out that she has been shot by live ammunition in the leg.

Oh my God, shes bleeding nonstop! one person shouts. Another shouts: Bandage it!

Photos and video after the incident show pools of blood on the sidewalk.
