Hundreds of small decorative balloons filled with hydrogen have exploded in flames at a political rally in Turkey, injuring 46 people. Dozens of balloons caught fire in the southern city of Malatya, local reporters say. The victims, who suffered burns, were rushed to a provincial hospital. Hundreds of balloons, about 40cms (16 inches) in height, were tied together and one apparently exploded while party officials were pumping hydrogen into it. In Turkey, highly flammable hydrogen is often put in balloons instead of helium because it is cheaper.
