Three people have been arrested for allegedly throwing firebombs at a synagogue in the Swedish city of Goteborg.
No one was injured in the attack late on Saturday during a youth event at the synagogue and the adjacent Jewish centre in Sweden's second-largest city.
On Sunday, Goteborg police spokesman Peter Nordengard said the attack was being investigated as attempted arson. No injuries were reported.
Officials have increased security around the synagogue and at a Jewish centre in capital of Stockholm.
Witness Allan Stutzinsky told the TT news agency that he saw a dozen masked youths who threw objects into the garden surrounding the synagogue.
