Reports stated that Luni had collided with another vessel several days prior to the sinking. Local officials believe the damage suffered by her hull from that earlier incident ultimately caused her to take on water and break apart.
Local media reports stated that the incident occurred at around the same time that explosions were heard around Bandar Abbas and nearby Qeshm Island. However, it has not yet been determined whether these were connected to the sinking.
Planes colliding, ships colliding. Who needs to bomb? They do a great job on their own.
