When the bombs started falling, they were almost beautiful — like the purple blossoms of the banana tree, Manwara and her sister Shamshida would recall later.

Their family was on the run, escaping the mortar fire that drove them from their home in Hari Fara, one of the last refuges for Myanmar’s Rohingya Muslim minority. They left their village in August, only to be hit by a rain of bombs released from drones. The strikes killed their parents. Their other three sisters, missing, are presumed dead.

They were among thousands of ethnic Rohingya families fleeing their villages this summer amid a new wave of targeted violence, a horrible echo of the ethnic cleansing by Myanmar’s military that killed thousands and exiled hundreds of thousands in 2017.
