A former Jewish student group leader has died in the crash of the Russian airliner over the Sinai in Egypt on Saturday.

27-year-old Anna Tishinskaya, a former program director for the Jewish student organization Hillel Russia, was en route from Sharm el-Sheikh to St. Petersburg aboard a charter flight operated by the Russian Kogalymavia airline when it crashed in the Sinai peninsula.

All 224 passengers, most of them Russian tourists, died.

Tishinskaya “was part of the family,” even though she no longer worked for Hillel, the group said in a statement.“Anya, you were incredibly talented, swift, fearless, sincere, kind and bright. You were a truly extraordinary person,” the statement read.

Tishinskaya graduated from St. Petersburg State University, where she studied history, according to a report on the Russian-language website isrageo.com. She took part in the activities of Hillel Russia and the Israeli Culture Center in St. Petersburg, where she was organizing events as late as 2012.

Radical Islamists from an affiliate group of Daesh claimed responsibility for downing the plane.

On Monday, the airline said the break-up of the plane was not caused by malfunction or pilot error.
