Under the Taliban, women risked being beaten if they did not wear full burqas or if they left the house without a male escort.
In 2009, Afghanistan passed a benchmark law criminalizing forced marriage, rape, beatings and other violence against women, but Amnesty and other campaigning groups say it is rarely enforced.
With international troops withdrawing next year, many Afghan women fear any advances made since 2001 will evaporate as the Taliban exert increasing influence at local and national levels.
Badghis Police Chief Sharaf said officers were investigating Halima’s killing, but no one had yet been arrested.
“We are trying to bring the perpetrators to justice,” he said, adding that authorities had only limited power in villages such as Kookchaheel.
“It is a volatile place and on the border between Badghis and Herat province, and the Taliban is also active,” he said.
