British authorities are investigating a series of vandalism incidents targeting properties linked to employees of defence companies, following claims by a pro-Palestinian activist group known as "The List." The group has asserted responsibility for multiple recent attacks involving executives and staff in the UK defence sector.

One incident occurred in Dunfermline, Scotland, where police responded on October 11 to reports of vandalism to a property and vehicles near a Leonardo site. Video footage posted on The List’s website showed an individual marking cars and building walls with red paint. Leonardo, a major defence contractor, confirmed an incident at the residence of one of its employees described by the group as a "key engineer." A company spokesperson said Leonardo was cooperating with the Counter Terrorism Police as part of the investigation.

In southern England, The List claimed responsibility for another attack in Fleet, Hampshire, targeting an executive linked to Ultra Intelligence & Communications, another defence firm. According to Hampshire police, a report was made on October 10 of criminal damage involving red paint thrown on a house and two car tyres slashed. The group alleges the executive targeted is the chief operating officer at Ultra and accused the company of collaborating with Israeli arms manufacturer Elbit Systems.

Authorities are treating the incidents as vandalism but are investigating potential links to broader activism or extremist actions. The Palestine Action group, which has conducted similar campaigns against defence companies such as Elbit and Leonardo, was designated as a terrorist organization by the UK government last year following multiple attacks.

At this time, police inquiries remain ongoing, with officials urging anyone with information related to the incidents to come forward. The investigations highlight ongoing tensions surrounding the UK defence sector’s connections to arms manufacturers and geopolitical conflicts.
