Police clashed with demonstrators trying to reach Iran’s embassies in London and Paris on Sunday.

French police used tear gas and employed anti-riot tactics to prevent hundreds of people protesting in the capital from marching on Tehran’s diplomatic mission, AFP reporters and eyewitnesses said.

In London, police said they made 12 arrests and five officers were “seriously injured” as demonstrators tried to break through barriers protecting Iran’s UK embassy.

The protesters in Paris had gathered for the second day running to express outrage at the death of Mahsa Amini following her arrest by Iran’s morality police — and to show solidarity with the protests that have erupted in Iran, at a cost of at least 41 lives.

Similar rallies in support of Iranian women have occurred around the world.

Ms Amini was detained for allegedly breaking headscarf rules. Officers reportedly beat her head with a baton and banged her head against one of their vehicles. However, police have said there is no evidence of any mistreatment and that she suffered "sudden heart failure".
