A top UN rights expert warned Monday that the crackdown on Myanmar's Rohingya minority bears "the hallmarks of genocide" and insisted the government should be held accountable.
Nearly 700,000 Rohingya Muslims have fled northern Rakhine state to Bangladesh since Myanmar launched a brutal crackdown on insurgents six months ago amid accounts of arson, murder and rape at the hands of soldiers and vigilante mobs in the mainly Buddhist country.
Myanmar has vehemently denied US and UN allegations of ethnic cleansing, insisting it was responding to attacks by the Arakan Rohingya Salvation Army in late August.
But on Monday, UN special rapporteur to Myanmar Yanghee Lee suggested that term was not strong enough.
"I am becoming more convinced that crimes committed ... bear the hallmarks of genocide, and call in the strongest terms for accountability," she told the UN Human Rights Council.
The South Korean academic, who has been barred from visiting Myanmar, called for a UN-backed investigation based in Bangladesh.
UN human rights chief Zeid Ra'ad Al Hussein also called last week for the creation of a new body tasked with preparing criminal indictments over atrocities committed in Myanmar.
The quest for accountability "must be aimed at the individuals who gave the orders and carried out violations against individuals and entire ethnic and religious groups," Lee said.
"The government leadership who did nothing to intervene, stop or condemn these acts must also be held accountable," she added.
Myanmar's civilian leader Aung San Suu Kyi has been the target of global vitriol for a perceived failure to stand up for the stateless minority.
But she remains a heroine for most of her compatriots, who largely consider the Rohingya as unwanted illegal immigrants from Bangladesh.
On Monday, Myanmar Ambassador Htin Lynn stressed to the rights council that Suu Kyi, a Nobel Peace Prize laureate, was committed to human rights.
"It is unreasonable to assert that our leadership, whose mission has human rights at its core, remains indifferent to the allegations of grave human rights violations," he said, insisting that the government was "ready to take action where there is clear evidence."
He meanwhile slammed Lee for presenting "sweeping allegations and unverified information," and insisted "there is a clear need to replace her."
Lee also called Monday for a "comprehensive review" of actions taken by the UN before, during and after the latest crackdowns on Rohingya in Myanmar.
"The violence and suffering calls not just for accountability but also for self-reflection by the UN, and the question: Could we have prevented this?" she said.
