According to NDTV, an
Indian Navy Submarine called Sindhughosh collided with a merchant navy ship in the Arabian Sea.
The submarine was trying to surface in Arabian sea near 300 km north of Mumbai.
Sindhughosh was on a routine fleet-level war game exercise when the collision occurred and slightly damaged its fin.
There were about 60 crew members on board and apparently it made back to the base in Mumbai without any help.
Its escape is termed miraculous since submarines normally sink on such occasions.
Navy officials are unwilling to confirm or deny the incident.
