The homes of defence industry figures are believed to have been targeted by pro-Palestinian activists who have sprayed paint on the buildings and damaged cars.
Police are investigating a string of vandalism incidents around the UK thought to be linked to a group called The List.
The Sunday Times reported that the group is targeting the homes of defence company executives who they accuse of aiding Israel’s military.
Among a number of incidents, the group claims to have targeted the home of a “key engineer” in Dunfermline, Fife, who was working at Leonardo UK’s site in Edinburgh.
The facility manufactures defence aerospace components and has previously been targeted by pro-Palestinian activists.
A video posted online is thought to be a recording of the incident at the home in Fife.
It shows a masked and hooded individual spraying paint on to three vehicles in a driveway and on to a house.
The group has posted statements and videos about its “actions” on a website registered in Iceland.
On October 12, the group said it had “escalated our actions against the home addresses of some of the most highly complicit companies in the ongoing genocide of our brothers and sisters in Palestine”.
It said it was targeting companies linked to the Israeli defence firm Elbit, saying: “Our list of complicit actors remains long, compiled through leaks, hacking and whistleblowers. If you work with Elbit, expect us.”
Police Scotland have said they are investigating two cases of vandalism to property and cars which were reported on the morning of Sunday, October 11.
One of these was in Dunfermline and the other was in South Queensferry, near Edinburgh.
The force said: “inquiries are ongoing.”
A similar incident in Fleet, Hampshire, in the early hours of October 10 is also thought to be connected to the group.
A spokesperson for Leonardo said: “We are aware of an incident which targeted the property of a Leonardo employee last weekend.
“The safety and wellbeing of our employees is our absolute priority, and we are providing support to the individual affected.
“We are also assisting Counter Terrorism Police with their ongoing investigation into this incident.”
