The government has received information that some individuals, vital scientific installations and some national monuments were under terrorist threat, Home Minister Shivraj Patil told the Rajya Sabha on Wednesday.
Security had been beefed up to guard against any terrorist attack, he said adding, such information was not given publicity as this could create a scare.
"There is information that important national monuments, important scientific installations, important modern industries and some individuals who are respected in the country have become vulnerable." Patil told Congress member Anand Sharma during Question Hour.
Stating that this information had been provided to state governments, he said all assistance would be provided to deal with the situation.
In reply to a query, he said Central Industrial Security Force had been entrusted with the task of providing security to airports, the Taj Mahal and the Ayodhya structure.
