The region in which the accident took place was in Riyanv village in Gorakhpur.
The woman who was bitten has been identified as Gita. She was on the phone with her husband who works in Thailand. The snake duo had entered the house and was playing on the bed.
Gita without noticing the snakes sat down on the bed. The snakes bit her and within minutes, she got unconscious.
Other family members rushed her to a nearby hospital where she died during treatment.
When the family members and neighbours returned to her room, the snakes were still playing on the bed. Angry neighbours beat the snakes to death.
Veterinary experts said that the snakes were apparently mating when the woman sat on them.
