A 14-year-old Afghan girl was beheaded and killed in an attack by two men, one of whom apparently asked her to marry him.

The attack happened Tuesday, a day before new legislation was introduced in Congress calling on the U.S. government to take steps to help protect Afghan women and girls as the U.S. military prepares to exit Afghanistan.

Gasitina, a student, was beheaded in the Imam Sahib district of Kunduz province. The attack was initially reported by local media, and was confirmed by Amnesty International researcher Horia Mosadiq in an email.

The girl was fetching water when she was accosted, according to reports. The men, who have not been identified, were arrested by police. The girl and her parents had refused a marriage proposal by one of the men, according to the Amnesty International report.
