The violence is worsening. There are horrific images of people dying in real time on YouTube video clips. In one, a sniper kills a young woman. I can't watch them anymore and won't post them here.
The Basij are monitoring the hospitals for injured. So many are encouraging wounded protesters to seek out support and help at foreign embassies.
Here is a map of those embassies in Tehran providing shelter and assistance.
The Embassies that are standing up thus far and doing the right thing are Australia, Finland, Germany, the United Kingdom, the Netherlands, Norway, Belgium, Mexico, Portugal, France, Switzerland (which represents the US). Canada is reportedly trying to find doctors to be helpful before opening doors to those who need help.
Why aren't Japan, China and Russia on this list?
