Crews resumed the search for nine people presumed killed at a Washington state paper mill where a chemical tank ruptured, resulting in one of the deadliest US workplace accidents in years.
The likely death toll rose to 11, including the missing, after another person who was injured died, authorities said.
Authorities said there was no hope of finding more survivors following Tuesday's tank failure at the Nippon Dynawave Packaging Co. in Longview, which also injured eight people.
The paper mill tank spilled over 500,000 gallons of a highly destructive chemical mixture used in paper manufacturing, known as 'white liquor.'
Fire officials said the search will be slow and methodical, with crews determined that the tank was stable enough to resume efforts to find the missing.
