The Navy has instituted a Board of Inquiry to probe the cause of the explosions and fire in INS Sindhurakshak which is expected to submit its report within four weeks. This was informed by the Defence Minister A K Antony in Rajya Sabha today. He said the accident was due to the possible ignition of armament. Mr. A K Antony said the outcome of the preliminary investigations yet to be established.

Meanwhile, rescuers from the Indian Navy today extricated one more body from INS Sindhurakshak, taking the number of victims recovered from the fire-devastated submarine to seven. 18 Navy personnel, including three officers, were on board the Russia-made submarine when a disturbing fire ripped through the frontline underwater craft following serial explosions on Tuesday midnight.
