Norwegian police are investigating an attack on the US embassy in Oslo that caused no injuries and only minor damage.
Amid the war against Iran, Norwegian Justice Minister Astri Aas-Hansen is deploying “significant resources” to search for potential multiple perpetrators.
“This is an unacceptable incident that we take very seriously,” she told Norwegian news agency NTB.
According to police, a “loud bang” was reported at the U.S. Embassy in Oslo early Sunday morning at 1 a.m. local time (7 p.m. ET Saturday), and eyewitnesses told Reuters they saw thick smoke at the entrance to the consular section.

“There was a very thick layer of smoke on the street,” said Sebastian Toerstad, 18, a high school student who was driving past the embassy at the time of the explosion.
“There was some damage to the entrance.”
According to the police, no explosives were found in the area.

“An on-site investigation was conducted using dogs, drones and a helicopter in search of one or more potential perpetrators,” Oslo police said in a statement.
PST, Norway’s police security service, called in additional personnel after the incident, but has not changed the country’s terror threat level, according to communications adviser Martin Bernsen.

“It’s way too early” for the investigation, he told TV 2 in Oslo.
