Rescuers in Italy are using explosives to try free a 32-year-old woman trapped in a cave deep underground, after she fell and sustained serious injuries during an expedition.
Ottavia Piana is stranded 585 metres (1,920 feet) underground in the Bueno Fonteno cave system, northeast of Bergamo city, as teams of rescuers, including medics and technicians, work to stabilise her condition and navigate the narrow, jagged passages that block her exit.
