6 men arrested for allegedly raping and killing teenage sisters in India

Six men were arrested Thursday in the northern Indian state of Uttar Pradesh for allegedly raping and killing two teenage girls whose bodies were found hanging from a tree a day earlier.

The 15- and 17-year-old girls belonged to the Dalit community, the lowest rung of India's rigid caste hierarchy, and were found hanging from a tree in a sugarcane field near their house in Lakhimpur Kheri district, police said.

Dalits — formerly known as "untouchables" — are victims of thousands of attacks each year.
