AN arms factory came under siege today when pro-Palestinian activists used a van to block its only entrance and exit.

Palestine Action activists sealed off Israeli-owned Elbit Systems’ research, development and manufacturing hub in Filton, Bristol.

Supporters used fire extinguishers filled with red paint to spray the site and raised a banner reading “Free the Filton 10” — a reference to the 10 imprisoned activists accused of causing more than £1 million damage at the site.
