A Human Rights group is claiming that a Buddhist mob rampaged through a minority Muslim Rohingya community in an isolated corner of Myanmar, hacking and stabbing residents including women and children, leaving anywhere from ten to 20 people dead.

This reportedly happened earlier in the week in northern Rakhine state, after a stand off between Muslims and authorities over some community members who went missing after landing in police custody.  The police returned in the darkness early the following morning, breaking down doors and looting livestock and other valuables.

The men reportedly fled, leaving women, children, and the elderly behind.  The massacre occurred sometime after that. Chris Lewa of the Arakan Project, an advocacy group that has been documenting abuses against members of the Rohinyga Muslim minority for more than a decade, said that the victims were stabbed instead of shot or beaten, indicating that a civilian mob rather than police was to blame.

Myanmar’s military denies that any massacre has taken place.

Myanmar is a predominantly Buddhist nation of some 60 million people.  Most of the country’s one million Muslims live in Rakhine province.
