WASHINGTON (Reuters) - U.S. Secretary of State Mike Pompeo said on Monday the United States strongly condemned Iran’s ‘unjust, barbaric” execution of Iranian dissident journalist Ruhollah Zam, who was convicted of fomenting violence during anti-government protests in 2017. Iran said last week that its Supreme Court had upheld the death sentence against Zam, who was captured in 2019 in circumstances that have not been officially disclosed, after years of living in exile in France.
