The Centre on Tuesday said it had intelligence information about the possibility of a militant attack at religious places and areas of national importance and claimed the swift action in Ayodhya was a result of the intelligence input.

"We had intelligence information in late May and meetings of all directors general of police and chiefs of central para-military forces were convened immediately after that," Union home secretary Vinod Kumar Duggal told reporters in Delhi.

The Intelligence spoke of some militant modules targetting religious places, he said.

Maintaining that no red alert had been issued in any part of the country, Duggal said the Centre had sent advisories to state chief secretaries to keep a close watch on "non-political and mischievous elements" who could use this incident to create communal disharmony.
