Asserting that the Maharashtra leader's statement was "not at all surprising", Javadekar said, "People in Maharashtra know that for four years and nine months, Pawar is a secularist and above caste but, three months before elections, he becomes absolutely casteist and communal.
"That is the politics of Pawar we see in every election. He targets caste of opposition leaders and makes communal appeals despite his opinion to the contrary... That is what has happened now."
The remarks come a day after Pawar attacked the BJP's prime ministerial candidate over the 2002 riots, saying that the entire country had seen the "mass murders" which took place in Gujarat.
Pawar had also questioned Modi's development model and his claim about changing the face of the country.
Earlier this month, Pawar had said that there was no need for a debate on the matter once courts had cleared Modi in 2002 riots cases.
There were also reports of Pawar having met Modi, but the NCP leader dismissed them.
Pawar had yesterday also alleged that the Gujarat Chief Minister had ignored certain sections of society in his quest for power.
Pawar's NCP is an important constituent of the Congress-led UPA government at the Centre and also an alliance partner in the Democratic Front government in Maharashtra.
