The longest cave system in the Indian subcontinent has been discovered in Meghalaya's Jaintia Hills district by an international team of spelaeologists, reports PTI. The team found a cave system over 22.20 km long, which surpasses the previous known record of 21.55 km of another system existing in the same district. "The linking of the Krem um im-Liat Prah cave system to Krem labbit (Khaidong) to create a single cave system of 22,202.65 m in length is the longest cave known to date in the Indian sub-continent,' the team members told a press conference.
