How swimming lessons are saving lives in Bangladesh
Cannot play media. Sorry, this media is not available in your territory.
In Bangladesh a child dies every 30 minutes from drowning.
With about 10,000 sq km of rivers, ponds and rice paddies, more children die from drowning than diseases.
Despite this, many boys don't learn to swim until they are teenagers and few girls are taught at all.
UNICEF and other partners have begun training local people how to teach swimming and rescue techniques and so far, 35,000 boys and girls have benefited.
