Verified video filmed during a reported electrical blackout in parts of Tehran shows hundreds of people waving their phones in Punak Square.
The blackout makes it hard to determine the location of the protest but some logos seen on nearby buildings helped us.
The internet shutdown has made it difficult to judge when the videos were filmed. This video did not appear publicly online before Saturday, but two videos we discovered on Sunday helped us verify it.

Protesters gather in Punak Square, Tehran
The first, posted at 15:11 GMT (19:11 in Tehran), shows people at the southeast corner of Punak Square, claiming to be filmed around an hour after dark in Tehran that day but warning of a 40-minute delay in uploading video using Starlink, a satellite-enabled internet service, to circumvent restrictions.
The second, posted 27 minutes later, shows hundreds in the square, cheering and clapping, and with more lights on than in Saturday’s video.
In both instances, we could quickly assess these were among the earliest, maybe the first, copies of the videos publicly online. The Iranian government has threatened to jam Starlink capabilities and we are trying to assess to what extent it is being used in Iran.
