British counterterrorism 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.

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.

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.

U.K. security officials have warned that Iran has sought to use criminal proxies to carry out hostile activity in the U.K., 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.

In the latest operations, police said detectives had arrested three men aged 24, 25 and 26 in Harpenden, north of London, on Sunday evening before releasing them on bail.

On Monday, a 25-year-old man had been arrested in Stevenage, north of London, ⁠while a 26-year-old and two women ages 50 and 59 had been arrested ⁠in a vehicle near the central English city of Birmingham and taken to a London police station, where they remained ⁠in ⁠custody.

On Tuesday morning, officers arrested a 39-year-old man at an address in west London under Britain's Terrorism Act 2000. Police said the arrest had been linked to an investigation after jars containing a nonhazardous substance had been found in Kensington Gardens in central London last week. Searches were continuing at a premises in east London, officers added.

Separately, a 17-year-old British teenage boy pleaded guilty on Tuesday to arson not endangering life, the BBC reported, following an attack on a synagogue in north London over the weekend. The fire caused minor damage and no injuries.

Since an attack last month on several ambulances belonging to a Jewish charity, counterterrorism police said they had arrested 23 people.
