Iran has blocked access to social media networks such as Instagram and WhatsApp amid protests over the death of a woman in police custody, according to residents and internet watchdog NetBlocks.
Significant internet outages were also reported across the country, with one of the largest mobile phone operators down, leaving millions of Iranians offline.
NetBlocks also reported a “nationwide loss of connectivity” on Iran’s main mobile phone provider and another company’s network.
WhatsApp servers were down across multiple internet providers, hours after Instagram’s services were blocked, London-based NetBlocks said.
The group’s data shows an almost total blackout of internet service in parts of Kurdistan province in western Iran since Monday, while the capital Tehran and other parts of the country have also faced blackouts since Friday, when protests erupted over first time.
