As flames tore through a 12-story hotel at a popular ski resort in northwestern Turkey, friends Esra Karakisa and Halime Cetin stood helpless as the horror unfolded before them, with people leaning out of smoke-filled rooms pleading for help and others making the harrowing decision to jump.

Witnesses have described standing helplessly and paralyzed by the horror of people screaming for help or jumping out of windows as flames tore through a 12-story hotel at a popular ski resort.

At least 66 people were killed and 51 injured as a fire ripped through a ski resort hotel in northwestern Turkey on Tuesday, according to the country’s interior ministry.
