The state of Uttar Pradesh in India has been put on high alert on the occasion of Shivratri, as there are inputs from the Intelligence Bureau (IB) on the possibility of terror attacks at temples and religious places. Heavy security has been put into force at important Shiv temples and special security checks have been in place at the Kashi Vishwanath temple in Varanasi. Apart from these, special vigil is being maintained on big and small temples in places like Kanpur, Agra, Lucknow, Faizabad, Gorakhpur, Azamgarh and other important places. Police has also been keeping a close eye on the 'kanwarias' who, as devotees carry holy Ganges water and walk bare foot to offer it to Shivlinga's as there was an apprehension that they may be targeted by terror outfits. So, the whole atmosphere on this auspicious day is really tense both to the administration and the devotees.
