Four children have died and five others are injured after falling from a bouncy castle that was blown into the air in Australia, police say, APA reports citing BBC.
The accident - caused by a wind gust - happened on Thursday at a primary school fun day in Devonport, Tasmania.
Police said the children had fallen from a height of about 10m (32ft). Two boys and two girls died.
Authorities did not give their ages but said all were in grades five or six - typically for children aged 10-12.
"A wind gust had reportedly caused the jumping castle and inflatable balls to lift into the air," Tasmanian Police Commissioner Darren Hine said.
"Our hearts are breaking for the families and the loved ones, schoolmates, teachers of these young people who were taken too soon."
Australian Prime Minister Scott Morrison described the accident as "unthinkably heartbreaking".
"Young children on a fun day out… and it turns to such horrific tragedy. At this time of the year, it just breaks your heart," he said.
Paramedics arrived quickly at Hillcrest Primary School after the accident at about 10.00 local time (23:00 Wednesday GMT).
The children were given first aid before being flown in helicopters to hospital.
Parents were alerted immediately following the incident, which happened on the last day of the school year.
ABC reporter Monte Bovill tweeted that locals "have been running to the school to collect their children".
One parent, speaking to a local newspaper, said the school had previously installed such floats on similar occasions with no problems.
"You wouldn't dream a fun activity day would end like this," the woman told the Hobart Mercury.
"We all feel so heartbroken for the parents involved. And feel guilty that we are also relieved our children were not injured."
A coroner's investigation was under way, police said.
Devonport, on Tasmania's northern coast, is a small port city with just under 30,000 residents.
