Terming Kumar's attitude as "callous", Modi said there was "no trace" of pain on the Chief Minister's face in the wake of the explosions and that he behaved as if some pleasant thing had happened.
The Gujarat Chief Minister alleged that Kumar was doing politics all the time after "stabbing" BJP in the back.
Drawing a contrast with Raman Singh, Modi said the Chhattisgarh Chief Minister had felt the pain when a Congress rally was attacked and stopped his Vikas Yatra. Singh had also ordered a judicial probe and went to victims' families to offer his condolences.
