LONDON, April 21 (Reuters) - British counter-terrorism police said on Tuesday they had arrested eight people in an investigation into a series of suspected arson attacks in London, including an alleged plot targeting a venue linked to the Jewish community.
Details of the Arrests
Seven of the arrests were made within the past 48 hours as part of a probe into a suspected conspiracy to commit arson, the police statement said.
While they did not identify a specific venue, police said an intended target was connected to the Jewish community.
Context: Rise in Threats Against Jewish Community
The arrests come as British police have been investigating a string of attacks on Jewish-linked sites in the capital, part of a wider rise in threats and criminal activity since the outbreak of the Israel-Gaza war in October 2023.
International Influence and Group Claims
UK security officials have warned that Iran has sought to use criminal proxies to carry out hostile activity in the UK, and the pro-Iranian group Harakat Ashab al-Yamin al-Islamiyya has claimed some of the latest attacks on social media.
Police made no connection between the group and the latest arrests.
