Four schoolchildren were killed and several others were seriously injured when a gust of wind blew their bouncy castle into the air at an end-of-term party in Australia Thursday.
Police said the pupils at a primary school in Devonport, northern Tasmania were celebrating the last week of class before the Christmas break when they were thrown from a height of about 10 meters (33 feet).
"I can now sadly confirm that four children have died and four are in a critical condition and one in a serious condition," Tasmanian police commissioner Darren Hine said.
The victims were two boys and two girls from grades five and six -- typically aged about 10-12 years old, AFP said.
Several rescue helicopters and ambulances rushed to the scene after the incident, which occurred around 10 am local time on an otherwise sunny, early summer day.
Images from the school showed attending police officers in tears, and a swathe of blue tarpaulin sheets shielding what officers described as "a very confronting and distressing scene".
A police investigation is under way. Distraught witnesses, friends, family, teachers and first responders are being offered counselling.
- 'Horrific tragedy' -
Australian Prime Minister Scott Morrison said the incident was "just shattering" and "unthinkably heartbreaking".
"Young children on a fun day out, together with their families and it turns to such horrific tragedy, at this time of year, it just breaks your heart," he said.
"I just want to say, to the parents and families and friends, all who were there, to the other young children there and witnessing these events, I just pray you'll have great family around you and great friends and you can come through this horrific tragedy."
The school had invited parents to volunteer for the event, which featured a wet play zone, a slide, an arts and crafts area, zorb balls and the bouncy castle.
"The purpose for the day is to celebrate a successful year and enjoy some fun activities with classmates," the school, Hillcrest Primary, posted on its Facebook page.
That post was followed by the update: "There has been an accident on site at our school. We are closing the school for the rest of the day."
"We ask that parents come to collect their children as a matter of urgency."
The school has around 200 students
Local weather services had forecast "light winds" for the area, which sits on Tasmania's rugged north coast, looking out across the frigid Bass Strait.
