Canada Train Blast: All Missing Believed Dead

Fifty people have now been confirmed dead or are presumed dead after a runaway freight train derailed and exploded in Canada.
Twenty bodies have already been found and officials are telling the families of 30 other people missing that all are believed to have been killed.
A railway boss has blamed an employee for failing to set the brakes properly.
Edward Burkhardt, chief executive of Rail World, made his comments during his first visit to the Quebec town of Lac-Megantic.
Mr Burkhardt, who arrived with a police escort and was heckled by angry residents, said a train engineer had been suspended without pay.
The boss said: "I think he did something wrong. It's hard to explain why someone didn't do something.
"We think he applied some hand brakes but the question is did he apply enough of them.
"He said he applied 11 hand brakes, we think that's not true. Initially we believed him but now we don't."
Mr Burkhardt does not suspect sabotage was involved.
An area of Lac-Megantic was flattened in the inferno caused by the crash, as a wall of fire tore through homes and businesses.
Some parts of the devastated scene have been too hot and dangerous to enter and find bodies even days after the disaster.
The blaze forced about 2,000 residents to flee their homes in the town, which has a population of 6,000. Most residents started returning on Tuesday.
The train, operated by Montreal, Maine and Atlantic Railway and carrying crude oil, had been stopped for a crew change in the nearby town of Nantes when it broke loose and hurtled downhill without a conductor towards Lac-Megantic.
It travelled for nearly seven miles before derailing at a curve in the tracks at 63mph and several wagons exploded.
Investigators are looking closely at a fire that happened on the train less than an hour before it became loose while stationery in Nantes.
The train's engine was shut down - standard operating procedure but one that might have disabled the brakes.
Police said a range of possibilities remain under investigation, including criminal negligence.
Some officials have raised the possibility the train was tampered with before the crash.
