Vienna Building Collapse After 'Explosion'
At least six people have been injured after a reported explosion caused a building collapse in Vienna.
It is thought other people could still be trapped inside the residential block in the 15th district of the Austrian capital, and sniffer dogs were being brought in to help in the search.
Witnesses said they heard a dull thud before the top two floors of the building fell in shortly after 10am, sending debris on to the street below.
Amateur footage showed a thick dust cloud enveloping the area moments after the collapse.
The cause of the possible blast is still unclear, according to the authorities.
Ted Knops, a 32-year-old resident, said: "There was a cloud of dust, and lots of people screaming and running.
"It was like a science-fiction movie when something comes bursting through the wall."
