Rescuers searched in bitter cold Sunday for victims buried when the roof of an exhibition hall in southern Poland collapsed on a racing pigeon show, killing at least 60 people and injuring 141. The death toll rose steadily through the early hours of Sunday as rescuers dug through the debris of the building, which collapsed at around 5:30 p.m. Saturday in the city of Katowice, The Associated Press reported. "Unfortunately we have more tragic information: 60 people have died," Andrzej Fiema, an official at the crisis management center organizing rescue said on TVN24 television shortly before 7 a.m. "This is information from all rescue services, so, fire, police and medical services." People who escaped said two emergency exits were open, but other exits were locked, leaving others trapped.
