Sri Lankan tsunami zone children learn to swim

On December 26, 2004, a tsunami swept across the Indian ocean, triggered by an earthquake off the coast of Sumatra.

In Sri Lanka, the wave killed more than 30,000 people - some of them women and children who were unable to swim.

The Swim Lanka project has been set up to give swimming lessons in some of the hardest-hit areas, in the hope of saving lives in future.
