Efforts underway to rescue 5 people trapped in Slovenia cave

Efforts were underway Sunday to rescue five people who became trapped in a cave in southwestern Slovenia, officials said.

Efforts were underway Sunday to rescue five people who became trapped in a cave in southwestern Slovenia when torrential rains caused water levels to rise in the subterranean labyrinth, cutting off their exit routes, officials said.

A 22-year-old Slovenian man, his parents and two guides became trapped in the Krizna Jama cave on Saturday morning, Sandi Curk, head of the Regional Civil Protection Headquarters for the Notranjska Region, told ABC News.

Curk said heavy rain in the area caused the cave's myriad of lakes to rise, stranding the tour group about 1 1/2 miles from the entrance to the cave.

Rescuers, according to Curk, will have to wait until the water level drops to extract the group.
