Security has been beefed up in Gujarat, particularly in the three major cities of Ahmedabad, Surat and Vadodara, following intelligence inputs that three terrorists may have sneaked into the State from Delhi with the aim of disrupting Independence Day celebrations by carrying out terror strikes.

Official sources said the information was received from the Intelligence Bureau on Saturday night.

The sources in the intelligence agency specifically named the three major cities as possible targets. An alert was sounded across the State after the recent serial bomb blasts in Pune.
