At least 13 people suffered minor injuries after a container ship near the Port of Long Beach leaked a chemical compound on Sunday morning, the United States Coast Guard said. The incident occurred around 9:27 a.m. and was first described as an unidentified substance leakage, in a tweet from the Long Beach Fire Department. The Department initially reported 11 injured dock workers, but later updated the number injured to 12. A firefighter was also injured due to a fall, the Coast Guard later said.
