 VIENNA: A rockslide on an Austrian mountain killed a 14-year-old Iraqi boy Sunday as he was climbing toward one of the biggest ice caves in the world on the Tennen mountains. The teenager was hit in the chest as he climbed at 1,600 meters 5,250 feet toward the Werfen ice caves, police said. Four hundred meters above the site, a rock of about two cubic meters in volume broke away after heavy rains on Saturday, said geologist Gerald Valentin.
