A blast followed by a fire hit an industrial park in the western German city of Leverkusen Tuesday, leaving one dead and several injured. Four people are still missing.
"We are deeply saddened by this tragic accident and the death of an employee," Chempark site operator Currenta said in a statement, adding that "rescue efforts continue at full speed" to find the workers still unaccounted for. Currenta said the explosion occurred at a tank farm that is part of its facility and that the fire had been put out. It added that a search was underway for four employees who were missing.

Chempark urged residents of Leverkusen, which lies 20 kilometers (13 miles) north of Cologne, to "go indoors and keep doors and windows closed."
