Iran detains '100 leaders' of petrol hike protests

Iran has arrested about 100 leaders of the protests against a hike in petrol prices, the judiciary says.
They were identified and detained in "various parts of the country" by Iran's powerful Revolutionary Guards.
The announcement came as the US placed sanctions on Iran's communications minister for restricting internet access during the unrest.
Amnesty International says more than 100 people were killed during the protests which hit several cities.
Other sources say the toll may be far higher. Iranian officials earlier this week confirmed 12 deaths.
