The missing Air France flight that left Rio de Janeiro but is feared to have crashed en route for Paris had at least one Jewish passenger on board.

An American strictly Orthodox website, VIN News, has carried a report saying that Serge (Shlomo) Anidjar, 40, a resident of Boulogne-Billancourt, in France, was on his way back home after spending three days in Brazil on a business trip.

The report said Mr. Anidjar was an active member of the Chabad Jewish community and has a wife and three children, the oldest of whom is 12, who attend local Jewish schools.

Rabbi Michael Sojcher told the website that “the family is devastated. Shlomo was a good man and I know him very well. This is a very hard time for us.”

Mr. Anidjar was director of finance and administration of Keyrus, a French global software company.

The website said a second French Jewish man was said to have been on the flight and has been reported missing and that the Paris Jewish community was tracking down his family.
