The attorney of the South African doctor whose family was killed in a Taliban attack in Kabul says she is still working at an Afghanistan hospital.

Teresa Conradie said Tuesday that Hannelie Groenewald, the wife of slain aid worker Werner Groenwald, is safe and remains in Kabul where she is continuing to work at a local hospital until her family's bodies are sent back to South Africa for burial.

Groenewald's husband Werner, 46, her son, Jean-Pierre, 17, and daughter, Rode, 15, were killed when three Taliban militants on Saturday stormed the office of a foreign aid group, where the family also lived.

The aid group has since closed its offices in Afghanistan.

South African authorities are assisting Groenewald with an emergency passport and returning her family's remains.
