Campaigners calling for tougher controls on the international arms trade gathered in Oxford city centre on Saturday to muster support from shoppers.

About 25 volunteers from Oxford's Oxfam and Amnesty International groups ran a stall outside the Westgate shopping centre to raise awareness of the arms trade, which they claim is out of control.

The volunteers asked shoppers to sign the 'Million Faces Petition' calling for tougher arms controls, by either having their photograph taken or by drawing a self-portrait.

The pictures will be displayed on the campaign website, which currently has more than 80,000 images on it of people from around the world.
