The UN envoy on sexual violence in conflict has said the widespread atrocities against Rohingya women and girls have been orchestrated and perpetrated by Myanmar's military and may amount to war crimes, crimes against humanity and genocide. <br/><br/>Pramila Patten, who met many Rohingya victims of sexual violence in Bangladesh camps during a visit this month, said she fully endorses the assessment by UN human rights chief Zeid Ra'ad Al Hussein that Rohingya have been victims of ethnic cleansing. <br/><br/>However, Myanmar's government has denied committing any atrocities as has its military. The government refused a request from Ms Patten to visit northern Rakhine state where many Rohingya lived.<br/><br/>
