There are unconfirmed reports of a fire at the home of Hossein Karroubi, son of the opposition leader Mehdi. The report, spotted by Tehran Bureau, appears on a website loyal to the regime.

Some 32 people have been injured in the festival so far, according to Isna citing a medical official.
There is still a notable absence of reliable images or video footage of what's happening. Either nothing much is occurring or the regime has successfully blocked news spreading. There are reports of restrictions on the internet in Iran and slow connection speeds.
