Mock weapons inspectors have destroyed fake guns to highlight an international campaign against the arms trade.
Gun Destruction Day was set up by the UN in 2001
Men in white overalls carried out their task in Devon on Saturday, to mark the United Nations Gun Destruction Day.
Organisers of the event in Plymouth's West Hoe Park hope it will prompt more people to get involved in the movement.
Joining them were members of Oxfam and the International Action Network on Small Arms, who want tighter control on the sale of weapons across the world.
Plymouth's newly-formed branch of Amnesty International was also at the demonstration. It claims a clampdown would also help to prevent gun crime filtering on to the streets of Britain.
Gun Destruction Day was established by the United Nations in 2001 and in some countries real weapons are being destroyed.
