Activists have called for stronger action to stop the “ongoing genocide” against the majority-Muslim Rohingya ethnic group after US Secretary of State Rex Tillerson said he was against “broad-based economic sanctions” against Myanmar. The world’s fastest-growing humanitarian crisis shows no signs of abating, two months after militant attacks triggered a military crackdown in Myanmar’s Rakhine State, Reuters reports. Southeast Asian leaders kept silent over accusations of ethnic cleansing carried out by Myanmar’s army during the ASEAN Summit last week, instead expressing support for the country’s efforts to bring peace and harmony to northern Rakhine state.
