Young men live in fear of being snatched off the streets and sold to Myanmar's army

"I worry, but I have to go out to work," says the 26-year-old tuk tuk driver, who asked that his real name be omitted out of fear for his safety. "My family call me all the time and remind me not to drive passengers too far; to be careful who I take as a passenger... I have to be vigilant all the time.

"People are panicked and frightened," he explains. "Some people I know have been taken."
