'The Servants of al-Mahdi')[1][2] is a British Twelver Shia religious movement based in London, England, led by Kuwaiti scholar Yasser Al-Habib.

[2] The group has been called anti-Sunni,[4] as it advocates for insulting Umar and Aishah, a companion and a wife of the Prophet.

[7] On 4 August 2022, members of this group carrying religious banners and flags protested at the Embassy of Azerbaijan in London.

[12] After Charity Commission became aware of this, it launched a statutory inquiry into the organisation[12] and on 7 April 2014 removed KMO from the list.

[12] On 8 November 2017, a private company limited by shares named Khoddam Al Mahdi Organisation Ltd. was incorporated.

The dormant company was wholly owned by Thamer Jundi Jassam, a Swedish citizen, who also served as its director.
