A man whose toddler son was shot dead in Turkey has met First Minister Alex Salmond to discuss a global treaty on the arms trade.

David Grimason, 40, from East Kilbride, has been campaigning for tighter controls on the trade in weapons since his two-year-old son Alistair was killed by a stray bullet during a gunfight which broke out at a cafe in the seaside village of Foca in 2003.
