Divers on Wednesday found the body of a man at a BASF chemical plant in western Germany where an explosion occurred on Monday, police said, bringing the death toll to three.
Prosecutors have ordered an autopsy be carried out on the remains, police in the federal state of Rhineland-Palatinate said in a statement.
BASF firefighters were caught in an explosion on Monday after responding to a small blaze near docks where tanker ships unload flammable liquids and liquified gases via systems of pipes.
Two firefighters were confirmed dead on Tuesday, with one person missing and more than 20 hurt, including six seriously.
The body found on Wednesday is believed to be that of the missing person.
“We have to assume that our fears have become a tragic certainty and lament a third death,” BASF board member Margret Suckale said in a statement.
