First lady boosts 'Let Girls Learn' initiative

Michelle Obama spoke on Thursday of a "crisis" gripping the world as she launched an initiative to help get girls into education on the second day of her trip to Japan.

The US first lady told an audience of women in Tokyo that 62 million girls around the world were being denied the right to go to school, which is a "profound waste of human potential".

"It is truly a crisis," said Obama.
