The United States is taking steps and considering a range of further actions over Myanmar's treatment of its Rohingya Muslim minority, including targeted sanctions under its Global Magnitsky law, the State Department said Monday.

"We express our gravest concern with recent events in Myanmar's Rakhine state and the violent, traumatic abuses Rohingya and other communities have endured," it said in a statement.

It added: "It is imperative that any individuals or entities responsible for atrocities, including non-state actors and vigilantes, be held accountable."
