"Hate speech is certainly, of course, a part of that", he added. Heavy artillery was being used in the offensives, U.N. Special Rapporteur Yanghee Lee told the U.N. Human Rights Council in Geneva.
During a press conference the chairman of the mission, Marzuki Darusman, said that social media had "substantively contributed to the level of acrimony" amongst the wider public, against Rohingya Muslims.
Crimes verging on genocide were being committed against the Rohingya minority in Myanmar, and those crimes bore "the fingerprints of the Myanmar government and of the global community", the United Nations special adviser on the prevention of genocide said on Tuesday.
The UN has been denied access to Rakhine since late a year ago, so both Lee and the fact-finding mission have been forced to conduct their investigations in Cox's Bazaar in Bangladesh, where hundreds of thousands of Rohingya are now living in refugee camps. Following the crackdown by Myanmar armed forces, around 700,000 people who belong to the Rohingya community have fled Myanmar and sought refuge in neighboring Bangladesh.
Myanmar's national security adviser, Thaung Tun, last week said his government did not support such atrocities.
She further adds, "I'm afraid that Facebook has now turned into a beast, and not what it originally intended".
The special rapporteur said she hoped to make official visits to India and China as part of her preparation to report to the General Assembly later this year, and said she remained hopeful the Myanmar government would revisit its decision and grant her access.
One of the most prominent nationalist Buddhist monks, Ashin Wirathu, whose profile was removed from Facebook, recently admitted that other social networks such as YouTube and Twitter do not work as well. "Hate speech and incitement to violence on social media is rampant, particularly on Facebook".
Facebook apparently took no action, however.
"Learning from experts on-the-ground, we will continue to refine the way in which we implement and promote awareness of our policies to ensure that our community is safe, especially people who may be vulnerable or under attack".
Beyond its global effort to bolster its content moderation by hiring more reviewers, it says it routinely removes hate speech content in the country, including Wirathu's account (although this only happened in late February), and that it has developed and promoted localized guidelines for using Facebook.
