In Iran, a government blackout of all internet traffic has entered its fifth day, leaving tens of millions of people accustomed to high-speed data cut off from the outside world. The blackout came amid a government crackdown on protests over soaring increases in the price of fuel. Amnesty International says more than 100 people were killed and over 1,000 arrested at protests in 21 cities, as Iranian forces fired live rounds into crowds from rooftops and helicopters. The fuel price hikes came after the Trump administration walked away from the Iran nuclear agreement last year, imposing harsh economic sanctions on Iran.
