Iran imposed an almost complete nationwide internet blackout on Sunday one of its most draconian attempts to cut off Iranians from each other and the rest of the world as widespread anti-government unrest roiled the streets of Tehran and other cities for a third day.

The death toll for the three days of protests rose to at least 12; hundreds were injured; and more than 1,000 people have been arrested, according to semiofficial news agencies like Fars News.
