Hurled stones shattered the window of a synagogue in Malmo, a city in southern Sweden.

The incident occurred earlier this month but was reported Tuesday in the Swedish media after police arrived at the building on Monday night because of a separate incident, which turned out to be a false alarm, the Aftonbladet daily reported.

Fredrik Sieradzki, a spokesman for the local Jewish community, told the TT news agency that the earlier incident happened on Oct. 7 and that it is not yet clear whether it was a hate crime targeting the congregation. There are no suspects.

Dozens of anti-Semitic incidents are recorded annually in Malmo, a city where first- and second- generation immigrants from the Middle East make up one-third of a population of roughly 300,000. Several hundred Jews live there.

Fred Kahn, a former leader of the local Jewish community, told JTA that most incidents are perpetrated by Muslims or Arabs.
