The 15th unniversary of the tragic disaster in Chorzow, Poland. ( 28 January 2006 ) 

66 people were killed when the snow-laden roof of an exhibition centre staging an event for international pigeon enthusiasts collapsed in the country's worst disaster in almost two decades.
After a night in which temperatures reached minus 15 Celsius (5 Fahrenheit), rescue workers began winding down their search for survivors among the rubble. There were over 700 people in the building at that time.
