Myanmar’s military engaged in “extensive and systematic” preparations for a bloody crackdown on Rohingya Muslims, a rights group said on Thursday, in a damning new report that it says justifies a genocide investigation, Agence France-Presse reports. The Military cracked down has driven nearly 700,000 people into Bangladesh. Andrew Gilmour, the U.N. assistant secretary-general for human rights, said Myanmar’s ethnic cleansing of Rohingya Muslims is continuing after a four-day visit to the Cox’s Bazar district in neighboring Bangladesh on early March. Myanmar denied the accusations, but on January its military has admitted that its soldiers murdered 10 captured Rohingya who it claims were “terrorists” during insurgent attacks at the beginning of September, after local Buddhist villagers forced the men into a grave they had dug.
