WASHINGTON — Abuses appear ‘‘normal and allowed’’ in Myanmar’s response to an armed uprising by Rohingya Muslims, a senior US official said in an interview, casting a pall over one of President Obama’s legacy foreign policy achievements.

Tom Malinowski, the State Department’s human rights chief, said a video of Myanmar police kicking and beating Rohingya — filmed by the police and recently surfaced on social media — suggests a disturbing pattern.

Obama and his advisers have long held up the former pariah nation’s US-backed shift from military rule as a breakthrough for democratic values in Southeast Asia. But the situation in Rakhine state makes the transition no straightforward success story.
