Violence Escalates In Iran: Girl Protestor Dies On Cam

I just got this video sent to me from a friend. It is pretty graphic. The whole situation is really sad, and pictures like this are not increasing the level of comfort of what will happen. A friend told me with close connections to Iran told me this will come down to showdown - either revolution or a blood bath. Or both.

One thing is for sure. It is a pretty explosive situation.

EDIT:
The video surfaced on Facebook roughly 3 hours ago. This is what it says there:

"مکان: خیابان کارگر، تقاطع خسروی و شهید صالحی، ساعت 7:20 مورخه 20 ژوئن، سی خرداد، Basij shots to death a young woman in Tehran's Saturday June 20th protests

At 19:05 June 20th
Place: Karekar Ave., at the corner crossing Khosravi St. and Salehi st.

A young woman who was standing aside with her father watching the protests was shot by a basij member hiding on the rooftop of a civilian house. He had clear shot at the girl and could not miss her. However, he aimed straight her heart. I am a doctor, so I rushed to try to save her. But the impact of the gunshot was so fierce that the bullet had blasted inside the victim's chest, and she died in less than 2 minutes.
The protests were going on about 1 kilometers away in the main street and some of the protesting crowd were running from tear gass used among them, towards Salehi St.

The film is shot by my friend who was standing beside me.

Please let the world know."
