On 9 March, a post on the social media network Telegram, reportedly from a group called Harakat Ashab al-Yamin al-Islamiya (HAYI), announced the beginning of “military operations” against US and Israeli interests.
Then, on Monday, a Telegram channel purporting to represent the group – whose name translates as the Islamic Movement of the Companions of the Right – made an unsubstantiated claim of responsibility for an arson attack on four Jewish ambulances in Golders Green, northwest London.
