Buddhist mobs killed at least 40 Muslims when they stormed a village in western Myanmar last week, hunting down residents with knives, a human rights group said, citing witness testimony and a wide network of local sources. The government has denied any deaths, except that of a police sergeant attacked by Rohingya Muslim villagers, but evidence of a massacre is mounting.

Matthew Smith, executive director of Fortify Rights, on Thursday sought access to Du Char Yar Tan village which has been emptied and sealed off since the Jan. 14 incident.
