Officials say a waitress who jumped out of a burning hotel at a popular ski resort has succumbed to her injuries, becoming the latest victim of tragedy that has shocked the nation and revived concerns over lax safety regulations in the country.

Tuesday's fire at the Grand Kartal Hotel in Kartalkaya left at least 79 people dead and 51 injured, happening during a particularly busy season.

The fire coincided with school holidays when many families from nearby Istanbul and Ankara head to the Bolu mountains to ski.
