Iranian dissident journalist Ruhollah Zam, who was convicted of fomenting violence during anti-government protests in 2017, was executed on Saturday, Iran's state television reported.
France reacted with anger to the hanging of the Paris-based journalist, which it called "barbaric and unacceptable" and said ran counter to Iran's international obligations.

Iran said on Tuesday its Supreme Court had upheld the death sentence against Zam, who was captured in 2019 after years of living in exile in France. His Amadnews feed had more than 1 million followers.
State TV said Zam, "director of the counter-revolutionary Amadnews network, was hanged this morning".
The French Foreign Ministry said in a statement: "France condemns in the strongest possible terms this serious breach of free expression and press freedom in Iran. This is a barbaric and unacceptable act that goes against the country's international commitments."
