Protesters in Iran have tried to break into a local government building in the southern province of Fars, on a fourth day of demonstrations sparked by a currency collapse.
Officials said three police officers were injured and four people arrested in the city of Fasa.
Confrontations were also reported in the western provinces of Hamedan and Lorestan.
The authorities in the capital, Tehran, had declared Wednesday a bank holiday - in an apparent effort to quell the unrest.
In video that emerged on social media and was verified by the BBC, a crowd is filmed breaking the gate of the governor's office in Fasa.
Then, in another post, security men are seen shooting in response. Clouds of tear gas rise in front of shuttered shops.
Across the country, schools, universities, and public institutions were closed due to the last-minute public holiday announced by the Iranian government.
It was ostensibly to save energy because of the cold weather, though it was seen by many Iranians as an attempt to contain the protests.
They began in Tehran on Sunday, among shopkeepers angered by another sharp fall in the value of the Iranian currency against the US dollar on the open market.
By Tuesday, university students had joined, spreading the demonstrations to several cities, with people chanting against the country's clerical rulers.
The protests have been the most widespread since an uprising in 2022 sparked by the death in custody of Mahsa Amini, a young woman accused by morality police of not wearing her veil properly. However, they have not reached the same scale.
Tight security measures are now reported in the areas of Tehran where the demonstrations began to prevent any escalation.
President Masoud Pezeshkian has expressed that his government will listen to the 'legitimate demands' of the protesters.
Conversely, the prosecutor general, Mohammad Movahedi-Azad, warned that attempts to create instability would be met with a 'decisive response.'
