At least 12 people have been killed in Iran since protests against fuel price rises erupted three days ago, officials have said.
Some unconfirmed reports suggest the number of dead is far higher. The situation on the streets is unclear on account of a nationwide internet shutdown. Iran has gone almost entirely offline as authorities try to stem the spread of nationwide protests that have gripped the country since Friday.
But demonstrations are reportedly continuing in some cities. The government said Monday had been "calmer", despite "some minor issues". Protesters took to the streets shortly after the government announced an increase in fuel prices by as much as 300%. Social media images showed banks, petrol stations and government buildings set ablaze by rioters. Some protesters chanted "down with Khamenei," according to videos, referring to the country's Supreme Leader Ayatollah Ali Khamenei.
Meanwhile, the powerful Revolutionary Guards demanded an end to the unrest. A statement said Iran's "sworn and evil enemies" had once again attempted to "sow discord", and that the force would "firmly deal with the continuation of any kind of insecurity or actions to disrupt the people's calm and comfort".
