"Diving operations by the Navy are in progress round the clock to attempt search for the personnel, assess the damage and also attempt to arrest leakages and ensure dewatering," he said.
The divers from Navy have entered the submarine but their access has remained limited to only some parts of the submarine due to heavy damage and flooding of compartments with obstructions from debris and structural distortions.
Breaches have been indicated in the "watertight integrity in the forward portion of the submarine hull" after inserting high pressure air as part of efforts to identify possible areas of water ingress.
