“It would be good” for anyone who so desires to leave Uman for “a vacation until it is safe,” Rabbi Ya’akov Djan, who is also an Israeli, wrote to Jews in the city where a predominantly Israeli Jewish population has grown up around the burial place of Nachman of Bratslav, an 18th-century Hasidic rabbi. But he added that anyone who does not wish to leave should not feel pressured to do so.

As for the city he is referencing:

Jewish community
A large Jewish community lived in Uman in the 18th and 19th centuries. During the Second World War, in 1941, the Battle of Uman took place in the vicinity of the town, where the German army encircled Soviet positions. The Germans deported the entire Jewish community, murdering some 17,000 Jews,[10] and completely destroyed the Jewish cemetery, burial place of the victims of the 1768 uprising as well as Rebbe Nachman of Breslov. After the war, a Breslov Hasid managed to locate the Rebbe's grave and preserved it when the Soviets turned the entire area into a housing project.[10]

Since the 1990s there has been a small, but growing, Jewish population in Uman, concentrated around Rebbe Nachman of Breslov tomb on Pushkina street. The local Jews are mostly involved in pilgrimage of Jewish tourists that arrive to the town. In 2018 the community saw large growth with about 10–20 families coming from Israel, accompanied by a small movement of young American couples. Newcomers to the city are concentrating around Skhidna St, with some toward Nova Uman area. In conjunction with this growth in the community, a new school of Yiddish was established.
