Blast kills 1, 4 still missing

An explosion at an industrial park for chemical companies in Germany killed at least one person Tuesday, with 31 others injured and four missing. Fire officials who tested the air said there did not appear to be a danger to nearby residents after authorities initially urged people to shelter inside.

The explosion at the waste management facility of the Chempark site in the city of Leverkusen, near Cologne, sent a large black cloud into the air. It took firefighters almost four hours to extinguish the fire.
