"As many as 30,000 people could have been killed in the streets of Iran on Jan. 8 and 9 alone, two senior officials of the country’s Ministry of Health told TIME—indicating a dramatic surge in the death toll. So many people were slaughtered by Iranian security services on that Thursday and Friday, it overwhelmed the state’s capacity to dispose of the dead. Stocks of body bags were exhausted, the officials said, and eighteen-wheel semi-trailers replaced ambulances."
I don't think.we will ever know the true number. Iran covers up as much as it can and with an Internet block very little ees escapes. Add that to little interest to actually find out.
