Patna, Oct 8 (IANS): Bihar Chief Minister Nitish Kumar on Thursday accused Prime Minister Narendra Modi of injecting communalism into the election campaign after the BJP leader attacked RJD chief Lalu Prasad.

"The real Modi on display - brazen attempt to add communal texture to Bihar polls but deafening silence on deplorable incident in Dadri," Nitish Kumar tweeted.

"All to see why Vajpayeeji was forced to remind him to follow Raj Dharma, but wonder who will be the Vajpayee today," he added.

Nitish Kumar said Modi first found fault with his DNA, described Bihar as a 'BIMARU' (sick) state and the people of Bihar as 'durbhagyashali' (unfortunate).

Now he called "Laluji" and the grand alliance of the Janata Dal-United, Rashtriya Janata Dal and the Congress as "shaitan".

"All this has exposed Modi's mindset, desperation and his thoughts about the people of Bihar," Nitish Kumar said.

Meanwhile, Lalu Prasad challenged the prime minister to show where and when he (Lalu) had said 'shaitan'. If Modi failed, he must apologize for dubbing Biharis as "devil", Lalu Prasad said.

"In the garb of attacking me, Modi described all Dalits and Other Backward Class as devil. In fact, he is frustrated and desperate following consolidation of Dalits and OBCs against him."

On Wednesday, Lalu Prasad questioned Modi's silence on the issue of reservation.

"Why did Modi remain silent on RSS chief Mohan Bhagwat's demand for a review of reservation in jobs and education for Dalits and OBCs?" the RJD leader asked.
