Story highlights The Rohingya are a stateless people in Myanmar

Yousafzai called out fellow Nobel laureate and the country's leader Aung San Suu Kyi for not doing enough to help them

(CNN) Malala Yousafzai, the youngest recipient of a Nobel Peace Prize, called on fellow laureate Aung San Suu Kyi to condemn the "tragic and shameful treatment" of Myanmar's Rohingya population.

The 20-year-old education advocate criticized Suu Kyi, the country's state councilor and de facto leader, for her silence on the plight of the Rohingya people, who have been fleeing a harsh crackdown by the Myanmar military.

"Over the last several years, I have repeatedly condemned this tragic and shameful treatment. I am still waiting for my fellow Nobel Laureate Aung San Suu Kyi to do the same," Yousafzai wrote. "The world is waiting and the Rohingya Muslims are waiting."

The Rohingya, a Muslim minority in predominantly Buddhist Myanmar, are considered some of the most persecuted people in the world. Myanmar, also known as Burma, considers them Bangladeshi while neighboring Bangladesh says they're Burmese, effectively leaving them without a state.

Recent violent clashes in Myanmar have killed hundreds while a mass exodus has seen more than 73,000 flee across the border since August 25, the United Nations said on Sunday.
