KUNDUZ, Afghanistan (CBSDC) — Afghan police arrest two men for allegedly beheading a 15-year-old girl after her father turned down a marriage proposal.

According to BBC News, the two men who proposed the arranged marriage and attacked her are relatives of the girl.

“Our investigation shows those who killed her were people who wanted to marry her,” a Kunduz province police official told the BBC.

The father did not want his daughter to get married because she was “too young to be engaged.”

CNN reports the girl was killed near her family’s home while bringing back water.

According to The Washington Post, dozens of Afghan women kill themselves each year in order to avoid arranged marriages.
