Myanmar's de facto leader Aung San Suu Kyi finally broke her silence on the Rohingya refugee crisis Tuesday, insisting that her country was not "afraid of international scrutiny."

But her speech in the nation's capital of Nyapyidaw drew widespread criticism: Suu Kyi did not denounce alleged atrocities against the Rohingya community and claimed the government needed more time investigate the exodus from Myanmar of more than 400,000 members of the minority Muslim group.
