The 22-year-old died in police custody in Tehran on September 16, 2022, three days after being jailed for not wearing her mandatory headscarf correctly.
Iranian officials claimed she suffered a heart attack in her cell.
Her death sparked major protests in Iran, attracting international attention to the struggles of Iranian women and piling pressure on the country’s regime.
The anniversary was marked by protests in London and around the world.
“We have taken direct action in relation to the individuals and institutions that have been involved in oppressing women in Iran,” he said.
“We have to understand that with a regime like the one in Tehran, we don’t have the traditional international diplomatic levers that we might have with other governments.
“But we make it absolutely clear, both directly to the Iranian leadership and more broadly on the international stage, that we completely reject their oppression of women, that we will continue to take action to highlight that, and also to apply sanctions to both the entities and the individuals who are driving this.”
