The victim’s full name was Negar Masoomi, her sister told CNN. Her killing was also confirmed to CNN by a local journalist in Ghor, who said she worked in Ghor prison and was eight months pregnant when she died.

The Taliban told CNN they were not involved in her death, but have launched an investigation.

Video obtained by CNN showed her son Mohammad Hanif giving his account of the murder, saying that the Taliban came inside the house where his family lives, then took himself and his brothers outside and tied them up.

“They killed our mother before our eyes. They killed her with a knife,” Hanif said.
