The BBC said Friday it was investigating a complaint by a prominent human rights campaigner in Britain who accuses its Iranian service of homophobia.
Peter Tatchell said he had contacted the BBC World Service after its Persian unit ran a blog that used derogatory language in Farsi to describe the gay community.
The post from October 2018 was amended last month after complaints, he said. But a video run on the BBC Persian TV station remains online, apparently mocking a Pride event in London in 2019.
"A freelance opinion piece has been updated with an acknowledgement on our website," a BBC spokesman told AFP.
