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.

Desperate guests at a Turkish ski resort that exploded into flames tried to escape using bedsheets as ropes hanging from the windows, while others died after trying to jump to safety.

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