Two brothers, aged 14 and 11, were seriously injured on Tuesday, when they fell several meters into a hole while touring the Hazan Caves in the Lachish district.
Lachish sub-district police said that the brothers were on a family trip with their parents and siblings in the caves, which are open to the public and include trails where visitors have to crawl to make their way through the passageways.
Both brothers fell several meters and suffered injuries across their bodies, including severe injuries to their heads. Both were rescued by firefighters and paramedics who made their way into the hole to give them first aid before pulling them out.
When they emerged from the cave, both boys were flown by helicopter to Jerusalem's Hadassah Ein Kerem Hospital.
Shortly after the brothers were rescued, police closed the site to visitors, and notified the managers of the site at the nearby Moshav Amatzia that they are opening an investigation into the upkeep of the site.
