Oslo police are searching for an armed, black-clad attacker who opened fire on the synagogue at Bergstien 13, St. Hanshaugen, at around 2.30 am today. The area has been cordoned off, and security at the Israeli embassy on Parkveien has also been reinforced, Aftenposten reports.
The shots were probably from an automatic weapon, and at least 11 bullets were fired. The bullet holes in the synagogue wall are clearly visible.
Reuters has some background to the incident:
Norway's Jewish community had asked its members not to speak Hebrew on the streets of Oslo after an assault on a man wearing a yarmulke in July. In August a man defecated on the steps of the Oslo synagogue and smashed two windows there.
