In an open letter to the United Nations Security Council on Thursday, 23 Nobel laureates and global leaders express their disappointment at what they describe as State Counselor Suu Kyi’s failure to ensure the rights of Rohingya.

They criticized Myanmar leader Aung San Suu Kyi for failing to secure the human rights of Rohingya Muslims in the country’s Rakhine State, while calling for immediate action to avoid ethnic cleansing and crimes against humanity.

“Despite repeated appeals to Aung San Suu Kyi, we are frustrated that she has not taken any initiative to ensure full and equal citizenship rights of the Rohingya,” the letter said.

“Ms. Suu Kyi is the leader and is the one with the primary responsibility to lead, and lead with courage, humanity and compassion,” it added.

This is while in recent weeks, over 27,000 people from the persecuted Muslim minority have fled a Burmese military operation in Rakhine state which was launched in response to the attack of border posts by armed groups.

Rohingya Muslims are loathed by many of Myanmar’s Buddhist majority.

More than 86 people have been killed in the crackdown which was launched after police posts were targeted near the border with Bangladesh on October 9.

Survivors of the harsh crackdown say they suffered rape, murder, and arson at the hands of the soldiers.

“The Rohingyas are among the world's most persecuted minorities, who, for decades, have been subjected to a campaign of marginalisation and dehumanisation,” the statement noted.
