Iran filmmaker Panahi fears Iranians' interests will be 'sacrificed' in US talks
Panahi, Iran's best-known director, offered support for anti-government protests last month in which thousands of people were killed by security forces, according to rights groups.
US President Donald Trump, having initially encouraged the demonstrations, has since focused his attention on making a deal with Iran's clerical leadership over the country's nuclear and missile programmes.
In an interview in Paris on Wednesday, Panahi told AFP that "whatever happens in these negotiations they will not be in the people's favour".
