New Delhi, May 30 (IANS) India has ordered a major security audit of its vital nuclear and oil installations across the country in the backdrop of the audacious May 22 terror attack on Pakistan’s Mehran naval airbase at Karachi.

Government sources said here Monday that the security audit would be carried out by the Intelligence Bureau in coordination with the Central Industrial Security Force (CISF), which guards most of the vital non-military infrastructure.

The installations to be audited include all important in-shore and off-shore oil infrastructure, nuclear establishments, airports and sea ports, the sources said.

The instructions for the security audit came following a review meeting called by Cabinet Secretary K.M. Chandrasekhar soon after the Karachi attack in which two of the five US-supplied P-3C Orion maritime patrol aircraft were destroyed.

‘The idea of the audit is to plug any gaps and to tighten the screws on the security apparatus in those installations,’ the sources said.

The defence installations are already on a state of high alert after the Mehran attack and their regular security inspections are continuing, sources added.
