A Scots father whose two-year-old son was killed by a gunman with an illegal weapon has welcomed the first-ever global treaty to regulate the international arms trade.

David Grimason, whose son Alistair was shot dead in his pram outside a cafe in Turkey 10 years ago, attended the Arms Trade Treaty talks at the United Nations in New York, as part of his work with Oxfam.

He has campaigned on the issue ever since Alistair was killed.

Campaigners say the vote marks "an incredible moment" signalling the dawn of a new era. The Control Arms coalition said the landmark vote sends a clear signal to gun-runners and human rights abusers that their time is up.

After six years of diplomatic negotiations, and more than 10 years of campaigning from civil society, governments at the UN voted for the Arms Trade Treaty by a resounding majority.

Mr Grimason said: "It's been an emotional day for me. It's an overwhelming majority of nations that have recognised the need for an Arms Trade Treaty.

"The world recognised it was needed. We overcame the sceptics today and by such an amazing majority, it's just incredible."
