Over 12,000 feared dead after Iran protests, as video shows bodies lined up at morgue: CBS News

Information trickling out of Iran on Tuesday suggests that a crackdown by authorities to end more than two weeks of widespread anti-government protests has likely been far more deadly than activists outside the country have reported. With phone lines opening back up for calls from inside the Islamic Republic, two sources, including one inside Iran, told CBS News on Tuesday that at least 12,000, and possibly as many as 20,000 people have been killed.

Britain's Foreign Secretary Yvette Cooper said in Parliament on Tuesday that the U.K. government believed there "may have been 2,000 people killed, there have been more. My fear is that the number may prove to be significantly higher."

The truth has been incredibly difficult to piece together due to Iran's hardline rulers cutting off internet access and phone service in the country for the last five days. While a complete internet shutdown in Iran remained in place for a fifth day, some Iranians were able to make phone calls out of the country on Tuesday, though it was still not possible to call into Iran from outside.

A source inside Iran who was able to call out told CBS News on Tuesday that activist groups working to compile a full death toll from the protests, based on reports from medical officials across the country, believed the toll was at least 12,000, and possibly as high as 20,000.

The same source said security forces were visiting the many private hospitals across Tehran, threatening staff to hand over the names and addresses of those being treated for injuries sustained in the protests.
