Intelligence in this regard has been shared by the Centre with the state government, the sources said.
They, however, said that the situation is not yet worrisome and the state authorities have also been informed about the necessary mechanism to counter the naxal activities.
The sources also said that the Centre had warned states about communal violence in different parts of the country and UP has been among the top states in this regard. They also added that the role of jehadi groups have been proven in many past cases of fanning communal violence in the country.
