Three Nobel Peace Prize winners yesterday urged fellow laureate Aung San Suu Kyi to speak out about violence against the Rohingya minority, warning she otherwise risks prosecution for "genocide", report agencies from Cox's Bazar. The trio -- Tawakkol Karman, Shirin Ebadi and Mairead Maguire -- implored the embattled Myanmar leader to "wake up" to the atrocities after visiting squalid camps in Bangladesh home to nearly one million Rohingya refugees.
