Sitting on the dirt floor in a flimsy bamboo shelter, Almas Khatun pulls a pink shawl from her face to reveal scars across her cheek and throat.

“I saw my family killed with my own eyes,” says the softly spoken 40-year-old survivor of Tula Toli, the most horrific massacre in a pogrom of indiscriminate killing, mass rape and arson targeting Rohingya Muslim civilians in Myanmar.

Almas says that every night she sees in her nightmares a soldier pulling her three-month-old baby from her lap and slashing open his stomach, moments before her house was set alight.

She wakes and weeps amid a sprawling mass of refugee camps carved into hillsides in south-eastern Bangladesh, reliving the morning of August 30. That was when soldiers ran – shooting and shouting obscenities – into Tula Toli, a picturesque village that sits in a bend where two rivers meet.

“They shot my old father, they put a log of wood in his mouth and then slit his throat,” Almas says, wiping tears from her eyes. “I keep thinking about my children. I couldn’t save them. They killed seven of my children, my husband and his two brothers.” Almas says 60 of her relatives who were living in three houses in the village are dead.

“Some were slaughtered by monks.”
