Gepranath Mahadev Mandir is a cave temple located on the banks of the Chambal, 25km from Kota town. It is a famous temple dedoicated to Lord Shiva and was visited by hundreds of locals last Sunday.
Rain caused a landslide which damaged the staircase or ladder(?) going down into the cave and destroyed the railings. One visitor, an engineering student, was killed and two others were hurt or also killed. 250 people were trapped inside the cave shrine, among them some 30 women and 50 children. The accident happened around 3pm on Sunday, and until dusk the rescue forces were not able to free the people. Food, water and other relief material was sent down into the cave by ropes. Then the rescue work was stopped until the next morning because of the darkness.

Update: One day later the numbers given before were corrected. 135 people, which were trapped in the cave, were rescued Monday during the morning. Four people at a time were lifted from the cave with a crane. It seems two people were killed during the accident.
