Two Breslov Hadisic Jews, including a 13-year-old boy, were lightly injured from shrapnel in a grenade explosion in Uman, Ukraine on Thursday.
Another grenade and drugs were seized during a search of a nearby building, from which Israel Police representatives in the city believe the grenade was thrown.
Tens of thousands of Hasidim visit Uman every year on Rosh Hashanah as part of a major pilgrimage to the grave of Rebbe Nachman of Breslov.
