LONDON, UNITED KINGDOM - 2021/08/28: An installation of hanging noose and red flower at Whitehall drawing attention to the 1988 Massacre of the Political Prisoners in Iran. A demonstration organised by supporters of the National Council of Resistance of Iran (NCRI) to protest against the inauguration of Iran's new president Ebrahim Raisi whom they accuse of being responsible for the mass execution of thousands of NCRI members in 1988 at Whitehall. The NCRI also called for the UK government to impose sanctions against Iran's leadership. (Photo by Loredana Sangiuliano/SOPA Images/LightRocket via Getty Images)
