The Bangladesh government has been urged to act to stop people "roof-riding" on its packed trains, a practice that campaigners say is causing increasing deaths and injuries.
Save the Children UK said widespread migration, in part caused by climate change, and fares that many could not afford are behind the growing practice. The charity's country director, Shumon Sengupta, said: "It's a growing problem. The population is increasing, and there has been huge migration to bigger cities.
"I've seen it with my own eyes, people falling off as they try to climb up. And then it happens when the train is moving."
Mr Sengupta said that the practice would not end until wider issues of poverty and climate change are tackled. Rising water levels are making low-lying areas uninhabitable.Reuse content
