Indian mourners carry coffins with the bodies of some of the 14 family members murdered at home, during their funeral in Mumbai on February 28, 2016.

A man in India stabbed 14 members of his own family to death, including seven children, before hanging himself, police said on Sunday, in one of the country's worst - and grizzliest - massacres in recent years.

Thirty five year-old Hasnin Warekar killed his parents and several of his sisters and their children at the family home shortly after midnight in the city of Thane, about 27 kms (16.8 miles) north of Mumbai, police spokesman Gajanan Kabdule said.

One of Warekar's sisters survived the attack, and is being treated for her injuries in hospital.
