A crowd in Bharatpur village in Dhanusa district, about 250km southeast of the Nepalese capital Kathmandu, on Sunday seized the woman, doused her with petrol and set her on fire after accusing her of trying to kidnap a baby from the village, the independent Kantipur Television said.
The woman, about 35 years old, died instantly, police said. She could not be identified as her body was charred beyond recognition.
Dhanusa in southern Nepal is one of several districts in the region that is plagued by growing lawlessness and violence.
Several armed groups operate in the area, and people have often taken law into their own hands in the absence of state authorities.
Several reports of violence against women have occurred in the district.
Last year, a female journalist, who wrote on violence against women, was stabbed to death in the same district.
The incident was seen as an attempt by organised groups and individuals to silence critics voicing their opposition to violence against women.

What else is one to expect from these Neanderthals.
The entire area should be exterminated from this vermin on the planet.
