Volunteer search and rescue teams on Thursday morning found a Jerusalem yeshiva student who went missing during a hike in the Judean Desert a day earlier.

Dozens of volunteers had joined police, firefighters and IDF soldiers in searching for the 22-year-old student after he was separated from his friends who lost their way hiking the dry river bed of Wadi Og near the Dead Sea.

Reports said the student was found unharmed, and was undergoing a medical examination at an IDF base in the area.

After getting lost Wednesday afternoon, the group called police for help, but by the time a rescue team arrived, the 22-year-old was nowhere to be found.

Firefighters, police and IDF soldiers scoured the area with jeeps, ATVs and a helicopter overnight Wednesday.

A police official told Israel Radio Thursday morning the search efforts had expanded to include a military helicopter and dozens of volunteers from the nearby Ein Gedi kibbutz, Arad, and the West Bank.

Authorities said the group was dehydrated when they were rescued, and they feared for the missing hiker’s life.
