Yesterday, Amnesty International withdrew its highest honour, the Ambassador of Conscience Award, from Suu Kyi, accusing her actions as "shameful betrayal of the values she once stood for".
Ms Suu Kyi (right) was unable to travel to accept Amnesty International's Ambassador of Conscience Award in 2009 but finally made it to Ireland for the presentation (above) in 2012.
"Amnesty International can not justify your continued status as a recipient of the Ambassador of Conscience award and so, with great sadness, we are hereby withdrawing it from you".
Aung San Suu Kyi, who is in Singapore for the ASEAN summit, has been widely criticised for her handling of the crisis.
She has also defended the jailing of two Reuters journalists investigating the killing of Rohingya Muslims.
Although the civilian government does not have control over the military, Aung San Suu Kyi and her office have shielded the security forces from accountability by dismissing, downplaying or denying allegations of human rights violations and by obstructing worldwide investigations into abuses.
"Someone who has been detained before should know the sufferings and should not inflict it on the hapless", Mahathir told reporters in a reference to Aung San Suu Kyi's long years of house arrest under Myanmar's military junta. "The state media, the civilian government that she has direct authority [over], has been very much complicit in publishing inflammatory and dehumanizing articles against the Rohingya".
Canada revoked her honorary citizenship last month and the US Holocaust Museum in March took back an award named after concentration camp survivor Elie Wiesel. We did not take this decision lightly. It was not an easy decision for us.
Amnesty International cited reasons behind the withdrawal of the award, in a statement on Tuesday.it said that she had failed to speak out and had safeguarded the security forces from "unaccountability" for the rampant violence against Rohingyas.
