Shots were fired at the Israeli embassy in Stockholm, the police force in the Swedish capital confirmed to the news agency TT on Wednesday morning.
Emergency calls were made on Tuesday evening due to a loud bang on the street where the embassy is located, in the Östermalm district of Stockholm.
The police said during the night that evidence suggested that the embassy had been hit by gunshots. No injuries were reported, and no one has been arrested yet.
Around the same time as the emergency calls, it became known that Iran had launched a major missile attack on Israel.
The Swedish police said they have increased security measures around Jewish and Israeli sites in the country following previous incidents at the embassy.
In May, shots were fired near the embassy, and in January, a hand grenade was thrown at the building, although it did not detonate.
According to TT, the Israeli foreign intelligence service Mossad believes that both incidents were Iranian contract jobs carried out by Swedish gang criminals. (dpa/NAN)
