Villepinte: Horrific moment of huge explosion at carnival in France

At least 30 people have been injured, four critically after an explosion rocked a busy French carnival.
Screaming spectators were thrown to the ground as the blasts shook the ground at the popular event.
The blast happened at the event known as the Yellow Carnival, in Villepinte, a Paris suburb about 11 miles from the centre, close to Charles De Gaulle airport.
Local authorities told French media that the blast was 'accidental', and was not terror related.
An aide to mayor Martine Valleton said the explosions were accidental.
'It's an unforeseeable and accidental incident,' the aide said.
The twin blasts happened during a Caribbean dance event during the carnival, and reportedly occurred after a effigy was set on fire.
Footage from the Villepinte Carnival show flames and plumes of smoke stretching into the sky after the explosions happened at about 5.30pm.
Emergency services are at the scene and have cordoned off the surrounding area, while the carnival was evacuated.
The cause of the explosion is not yet clear, but it is believed carnival-goers were setting fire to an effigy called Mr Carnaval, a giant puppet in the shape of a man made from straw and sticks.
Witnesses reported hearing loud bangs as the fire took hold, just after the carnival parade had started.
The blasts sparked panic among the crowds as several people were harmed by flying debris.
Witnesses described scenes of horror and panicked crowds and reported seeing 'a man with a broken arm' and 'a child with blood on his face'.
Others talked of 'people running around to find their children' in the wake of the explosions.
