LONDON: Four people in the UK were arrested after a group of pro-Palestine activists broke through the gates of a defense manufacturer on Tuesday, The Independent reported.

Footage released by a group called Palestinian Martyrs shows members breaking into the Moog Aircraft Group factory in the city of Wolverhampton at 3:50 a.m.

Activists set off red flares and climbed on to the roof of the facility after smashing through two white barriers using a four-wheel drive.

The factory suffered major damage to sky lights and solar panels, Staffordshire Police said in a statement, adding that four people were arrested on suspicion of criminal damage.

“A number of individuals had entered a manufacturing building and gained access to the roof,” the statement said.
