India, June 26 -- Jan Suraaj Party chief Prashant Kishor on Thursday launched a sharp attack at Rahul Gandhi, accusing the Congress leader of mocking Biharis while sitting in Delhi and dared him to spend a night in a village in Bihar.

The remark comes as the political heat intensifies in Bihar ahead of the assembly polls in the state, scheduled later this year.

"Rahul ji keeps coming and going from Bihar, but doesn't really undertake any Yatra. If Rahul Gandhi has ever spent even one night in a village in Bihar, then tell me. If he can spend just one night in a village, we'll accept it," Rahul Gandhi told news agency ANI in an interview.

"You sit in Delhi and laugh at Biharis. Then you come here to lecture us," he said.

Kishor also hi...
