3 of cruise-ship crew killed by toxic sewer gas

LOS ANGELES (AP) — Three members of a cruise ship crew were killed by toxic sewer gas Friday as they repaired a waste pipe aboard the ship that had just returned to the Port of Los Angeles.

No passengers were injured, but 19 other crew members from Royal Caribbean's Monarch of the Seas were examined for possible exposure to the toxic gas, authorities said.

Passengers were leaving the ship at the time of the incident, the company said.
