Families face agonising wait as investigators work to identify at least 40 people killed, many others wounded in blaze.
Investigators say sparklers placed in champagne bottles were held too close to the ceiling and may have ignited the material, triggering a fast-moving fire that killed at least 40 people and injured 119 others. Survivors described chaos and panic as flames spread rapidly through the crowded bar in the Swiss Alps. NBC News’ Daniele Hamamdjian reports.
Images recorded by partygoers show sparklers stuck in the top of champagne bottles held close to the basement bar's low ceiling, which was covered with soundproofing foam material.
