Students at several universities in Iran have staged anti-government protests – the first such rallies on this scale since last month’s deadly crackdown by the authorities.
The BBC has verified footage of demonstrators marching on the campus of the Sharif University of Technology in the capital Tehran on Saturday. Scuffles were later seen breaking out between them and government supporters.
A sit-in was held at another Tehran university, and a rally reported in the north-east. Students were honouring thousands of those killed in mass protests in January.
The US has been building up its military presence near Iran, and President Donald Trump has said he is considering a limited military strike.
The US and its European allies suspect that Iran is moving towards the development of a nuclear weapon, something Iran has always denied.
US and Iranian officials met in Switzerland on Tuesday and said progress had been made in talks aimed at curbing Iran’s nuclear programme.
But despite the reported progress, Trump said afterwards that the world would find out “over the next, probably, 10 days” whether a deal would be reached with Iran or the US would take military action.
The US leader has supported protesters in the past – at one stage appearing to encourage them with a promise that “help is on its way”.
Footage verified by the BBC shows hundreds of protesters peacefully marching on the campus of the Sharif University of Technology at the start of a new semester on Saturday.
The crowds chanted “death to the dictator” – a reference to Supreme Leader Ayatollah Ali Khamenei – and other anti-government slogans.
A separate crowd of supporters of a rival pro-government rally – many with national Iranian flags – are seen nearby at the beginning of the video. Scuffles are later seen breaking out between the two camps.
Verified photos have also emerged showing a peaceful sit-in protest at the capital’s Shahid Beheshti University.
The BBC has also verified footage from another Tehran university, Amir Kabir University of Technology, showing chanting against the government.
In Mashhad, Iran’s second-largest city in the north-east, local students reportedly chanted: “Freedom, freedom” and “Students, shout, shout for your rights”.
It is not immediately clear whether any demonstrators have been arrested.
There have been reports of protests continuing on Sunday.
Last month’s protests began over economic grievances and soon spread to become the largest since the 1979 Islamic Revolution.
