Couples in India dying in 'honour killings'Trend that's spreading: Every year in India, hundreds of couples die in ‘honour killings'
Many Hindus believe women should marry partners of the same ancient caste.
Marrying someone from a different social class — Rajni's transgression — is also often outlawed. But perhaps the most forbidden love involves a match between partners of the same gotra, members of a single caste believed to have descended from a common male ancestor. That is considered incestuous.
In India, the government has decried “honour killings” and vows to stamp them out. But some say the promise of a crackdown is half-hearted.
