The incident took place during the ongoing traditional Nations' Fair and a week before Lithuania marks its Day of Remembrance for Jewish Victims of Genocide, according to Faina Kukliansky, head of LŽB.

"We have not seen so clearly expressed anti-Semitism for a long time, having in mind all the circumstances, the Nation's Fair and the genocide commemoration," she said. "There were children inside our building and they were going to join the Nations' Fair. In other words, this is how we got congratulated with the Nations' Fair. The mood is dismal, I'm out of words."

The police has been informed and the Jewish community plans to file an official complaint.

Kukliansky, however, called for more involvement of the state to protect the Jewish community.

"There's state protection everywhere [else in the world]. It all starts with small things and they evolve into big things and it's negligent to ignore it," the LŽB chairwoman said.

Lithuanian Minister of Foreign Affairs Linas Linkevičius has already condemned the incident, calling it deplorable.

"It's a deplorable incident that needs a swift investigation. It’s completely non-natural for us, and really such incidents have not been characteristic of us and do not do us credit, and, of course, they need to be investigated as soon as possible and prevented," he told BNS.

In early August, the JCL temporarily closed its headquarters and the Vilnius synagogue in response to threats. It was decided several days later to resume normal activity.
