Youths take plunge with lifesaving lessons

After her eldest son Amanto became one of the 50 children to drown on an average day in Bangladesh, Jahanara Anwar was determined that his younger brother join the world's biggest swimming lesson.

"I'd promised to send him to a swimming center once his exams were over but didn't realize how important it was," she said, recalling the day in 2011 when Amanto, 14, went to play in a nearby canal and never came home.

"Now there can be no doubt how important it is ... I don't want any mother to suffer the agony I've been through."
