The BBC reports that Iran has moved to restrict social media networks that have been used to organize four days of anti-establishment protests.
The restrictions on messaging app ‘Telegram’ and photo sharing app ‘Instagram’ are "temporary", state news agency Irib reported.
The decision was taken "to maintain tranquility and security of society", a source was quoted as saying.
The protests have been the biggest show of dissent since huge rallies in 2009.
They began in the northeast as an outcry against economic hardship and rising prices, but turned political in many places, with slogans chanted against Supreme Leader Ayatollah Ali Khamenei, President Hassan Rouhani and Iran's interventionist foreign policy in the region.
After violence flared in many places on Saturday, it is unclear how many demonstrations are occurring on Sunday. Small crowds have gathered in Tehran and police have used water cannon to disperse protesters at a major intersection that was captured in a video obtained by BBC Persian.
