Twin Italian-Jewish sisters, both in their teens, were confirmed on Sunday to be among the 40 fatalities from a fire that broke out at a hotel in Switzerland at a New Year’s party just after midnight Friday.

Another Jewish teenage girl, Charlotte Niddam, who is an Israeli citizen, is still missing.

Sisters Alicia and Diana Gunst were initially considered missing in the ski town of Crans-Montana in the Swiss Alps, but their bodies were identified along with 16 others out of the known 40 dead, a spokesperson for the Swiss Federation of Jewish Communities (SIG) told JNS.
