Watch: Massive explosion in Jersey leaves one dead, many missing

One person was killed and several others were missing after a "devastating" explosion Saturday at a block of flats in Jersey's capital St Helier, police on the Channel island said.
A fire was put out but emergency services are still conducting "significant work" at the scene of the flattened building, the police said, as a line of ambulances queued up.
Fire crews mobilised after residents reported smelling gas, before the explosion at around 4:00 am (0400 GMT), Jersey police chief Robin Smith told reporters. 
"We have a three-storey building that has completely collapsed -– described from a demolition point of view as a pancake that has dropped almost straight down," he said. 

"There is also damage to a nearby building as well, another block of flats that the fire service needs to make safe. It is a pretty devastating scene, I regret to say."
Photographs on social media showed thick smoke billowing above the blaze in St Helier before dawn. 
Smith said that "around a dozen" people were missing, "but you will appreciate also that number could fluctuate".
"Specialist resources" have been mobilised to find anyone trapped in the rubble, according to the police.
