A Jewish community in Ukraine says nationalist groups are seeking to thwart the construction of a synagogue and have erected crosses on the site. The chief rabbi of the southern city of Poltava says a group of nationalist activists have put up seven wooden Orthodox crosses on land allocated by local authorities for the synagogue. Rabbi Yosef Yitzchak Segal said Tuesday it was a provocation aimed at stirring religious hatred in the city. No group has claimed responsibility. Jewish groups complain that anti-Semitism persists in Ukraine and there is little respect for Jewish cemeteries and memorial sites.
