Photos published on social media reveal the entrance and internal chambers of the cave, where visibility is drastically reduced by sediment.

The official statement from DAN Europe indicates that the divers became disoriented. “The divers were unable to find their way back to the exit, most likely due to disorientation within the cave system,” the organization noted.

“It is strongly recommended not to enter this cave system without proper authorization, specialized cave diving training, and the appropriate technical equipment,” the entity warned.

Furthermore, they clarified that this is a preliminary report. The definitive causes of this inexplicable tragedy will be determined by police authorities.

“They could not find their way back to the exit, most likely due to disorientation within the cave system,” stated the Divers Alert Network Europe.
