Bound together, the 10 Rohingya captives watched their Buddhist neighbors dig a grave. Soon afterward, on the morning of Sept. 2, all 10 lay dead. At least two were hacked to death by Buddhist villagers. The rest were shot by soldiers, two of the gravediggers said.

The killings marked another episode in the violence sweeping Myanmar's northern Rakhine State. The Rohingya accuse the army of arson, rapes and killings. The United Nations has said the army may have committed genocide. Myanmar says its "clearance operation" is a legitimate response to attacks by insurgents.

Rohingya trace their presence in Rakhine back centuries. But most people in majority-Buddhist Myanmar consider them to be unwanted Muslim immigrants from Bangladesh. The army refers to the Rohingya as "Bengalis," and most lack citizenship. In recent years, the government has confined more than 100,000 Rohingya in camps where they have limited access to food, medicine and education. Nearly 690,000 Rohingya have fled their villages and crossed the border into Bangladesh since August.
