Officials in Turkey say that a fire has raged through a 12-story hotel at a popular ski resort in the northwestern part of the country during a school holiday, killing at least 76 people.

Turkey has detained nine people, including the owner of the hotel, in connection with a deadly fire that claimed the lives of 76 people and injured dozens at a ski resort in western Turkey, Interior Minister Ali Yerlikaya said early Wednesday.

The investigation is critical for not only understanding what happened, but for ensuring it never happens again, said an attorney for 300 Altadena residents.

As the Eaton fire spread, many areas were notified of evacuation warnings and orders well in advance. In the heart of Altadena, where all 17 reported deaths occurred, evacuation orders came hours after fire did.

All of the 17 deaths confirmed in the Eaton Fire occurred in an area where an evacuation order was delayed for hours after the blaze erupted, according to a Los Angeles Times report.
