Fifteen-year-old Charlotte Niddam was identified as the Israeli who the Foreign Ministry noted was out of contact following the disaster at a Swiss ski resort on Saturday.
Niddam, who has also lived in Britain and France, has been out of contact since the incident and is listed among the missing in the deadly fire that broke out on New Year's Eve at the Le Constellation bar at Crans-Montana ski resort which killed around 40 people and injured about 119 others.
Niddam, until recently, lived in Bushey, just outside London, and studied at the private Jewish secondary school Immanuel College.
"We urgently ask our school community to come together to support Charlotte Niddam," the school said in a press statement. "The families have asked that we all keep them in our thoughts and prayers during this difficult time."
"We are all praying for a miracle for Charlotte and the others, and want the families to feel the full strength of the support of the Immanuel College community."
As far as it is known, Niddam had been staying in the area of the ski resort, where she worked as a babysitter, offering her services through the resort's website.
Niddam's friends and family published photos of her on social media, calling for help in locating her.
Israel's Foreign Ministry said that a team from the Israeli Embassy is operating on scene and is in continuous contact with local authorities. Additionally, the Israelis Abroad Department at the Foreign Ministry and the embassy are in touch with the Niddam family.
Members of the local community and the family are awaiting news as the process of identifying victims continues, in part due to the severe condition of those affected.
What happened during the Swiss disaster on New Year's Eve?
The fire broke out at around 1:30 a.m., apparently after sparks from fireworks attached to champagne bottles ignited the wooden ceiling of the bar. The fire spread rapidly and caused panic and congestion at the exits, leading to a large number of casualties.
Swiss authorities confirmed on Saturday that a criminal investigation has been opened against the bar's managers. The two managers are suspected of causing death by negligence, bodily harm by negligence, and causing a fire by negligence, police said in a statement.
Earlier on Saturday, Swiss police said they successfully identified four bodies, releasing them for burial.
These were identified as two Swiss women, aged 21 and 16, and two Swiss men, aged 18 and 16.
Further, Italian golfer Emanuele Galfini perished in the disaster, reports stated on Friday.
