I was surprised the article and headline didn't use the world genocide. But it looks like it is consistent with other NY Times articles from the time.

This article was published (Nov. 6, 2018) after the UN official declared it a genocide. Yet, genocide doesn't appear in the article.

UN official convinced of Myanmar Rohingya ‘genocide’ - March 12, 2018 https://www.cnn.com/2018/03/12/asia/myanmar-rohingya-un-viol...

Another NY Times article from August 2018 also is reluctant to call it a genocide.

>United Nations officials have raised the prospect that the violence could be considered genocide, and officials at the United States State Department have debated using the term, according to American diplomats.
