Nine people are dead after a small plane carrying parachutists crashed in Sweden.
Witnesses watched in horror as the aricraft plummeted into a river near an island outside the northern city of Umea, on Sweden's eastern coastline, killing all aboard.
One witness said he heard the strange sound and watched as the plane plummeted, nose-first, then crashed out of sight with a loud 'bang'.
Axel Pettersson, 16, told Aftonbladet he was sitting on the couch at his home near Umea Airport eating when heard a sound from the skies becoming higher, and higher-pitched.

Axel said he is used to the sounds of the planes arriving and departing, but described the noise as like one he had never heard before.
He went outside and saw a plane circling.
He began filming, and seconds later captured the plane plummeting rapidly.
He said he heard it crash with a loud "bang" then everything went quiet.
Axel said his pulse rose and he barely breathed, thinking: "what the hell is happening now, what the hell is happening now, what do I do now".
He called for his parents who immediately alerted emergency services.
Authorities in Sweden said the plane had taken off from Umea Airport shortly after 1.30pm and sounded an alarm at 2.12pm.
Local police told Sweden's SVT reports of the crash came in about 2pm.
It crashed in the river near the island of Storsandskar, which is located about 2km from Umea airport.
A police spokesman said early reports suggested the plane had gone down in the river in an area south of the airport, on Storsandskar.
The aircraft was said to have been a single-engine and was carrying parachutists.
Witnesses living nearby the airport told Expressen they had heard a 'bang' and saw the plane dip.
Another witness said she saw the plane spin with its nose facing downwards before it plummeted.
"We are already on the scene with a rescue team which is assisting the ambulance and we have opened a location, together with aid organisations, to give psychological and social care," Conny Qvarfordt from the local rescue services told Sweden's TT newswire, reports Sweden's The Local.
"It's a parachute plane, and something seems to have happened just after take-off."
Umea Airport operator Swedavia, said the plane was a GippsAero GA8 Airvan, which is a single-engine eight-seater utility aircraft, similar to a Cessna.
