Norwegian police said they are reinforcing security measures to protect both the Iranian diaspora community and the Jewish community in Norway.
Authorities said they are also in contact with the US embassy and are cooperating closely as part of the security response.
Swiss Defense Minister Martin Pfister said the United States, Israel and Iran had all violated international law in the conflict, arguing that each had breached the prohibition on the use of force.
“The Federal Council is of the opinion that the attack on Iran constitutes a violation of international law,” Pfister said in an interview published on Sunday, referring to the Swiss cabinet.
“In our view it constitutes a violation on the prohibition of violence,” he added.
Pfister made clear he was referring not only to the attack on Iran but to all sides that had failed to comply with that prohibition, including Washington, Israel and Tehran.
“The Americans and Israel have attacked Iran from the air. In doing so, they, like Iran, violated international law,” he said.
He called on all parties to halt the fighting to protect civilians.
His comments add to broader European concern over the legal basis for the war. German Vice Chancellor Lars Klingbeil said he had “serious doubts that this war is legitimate under international law” and rejected any potential German participation.
“I say clearly: this is not our war. We will not participate in this war,” Klingbeil said.
Spain has also denounced the US and Israeli bombings as reckless and illegal.

Major General Abdolrahim Abdollahi, commander of Iran’s Khatam al-Anbiya Central Headquarters, said Iran would continue the war until the enemy is forced into regret and brought down.
He said Iran’s weapons were now more advanced than before and had high accuracy and resilience.
Abdollahi also said the United States and Israel had repeatedly claimed to know the size of Iran’s missile arsenal, adding: “We tell them to count Iran’s missiles on the battlefield.”
At least four people were killed when an Israeli strike hit an apartment in the Ramada hotel building in central Beirut early on Sunday, with Israel saying the attack targeted Iranian commanders operating in the Lebanese capital.
The Israeli military said it was targeting commanders from the Revolutionary Guards’ Quds Force who it said were operating in Lebanon to plan attacks against Israel while also coordinating with the IRGC in Iran.
“The commanders of the Quds Force's Lebanon Corps operated to advance terror attacks against the state of Israel and its civilians, while operating simultaneously for the IRGC in Iran,” the military said in a statement.
Later in the day, sources cited by Saudi-owned Al Hadath said five Iranian members of the Lebanon branch of the Quds Force were assassinated in the strike.
The sources identified the dead as Majid Hosseini, the financial officer of the Lebanon branch of the Quds Force; Ali Biazaar, its intelligence officer; Hossein Ahmadlou, head of what they described as the branch’s “Zionist file”; and Ahmad Rasouli, head of the Intelligence Department in the Palestine Corps.
Lebanon’s health ministry said 10 people were injured in the strike in Beirut’s Raouche district. The attack hit a corner suite on the fourth floor of the hotel building, shattering windows and blackening the facade, according to Reuters.
US President Donald Trump said Britain was giving “serious thought” to sending two aircraft carriers to the Middle East, but made clear he did not believe Washington needed British help in the war with Iran.
“The United Kingdom, our once Great Ally, maybe the Greatest of them all, is finally giving serious thought to sending two aircraft carriers to the Middle East,” Trump wrote on Truth Social.
“That’s OK, Prime Minister Starmer, we don’t need them any longer – But we will remember. We don’t need people that join Wars after we’ve already won!”
Trump’s remarks came after Britain’s defense ministry said it was preparing the aircraft carrier Prince of Wales for possible deployment, although no final decision has been taken.
British Prime Minister Keir Starmer has defended his earlier refusal to allow US forces to use British bases for initial strikes on Iran, saying he wanted to ensure any action was legal and properly planned.
Responding to Trump’s comments, British Foreign Secretary Yvette Cooper told Sky News: “The thing I’ve learned doing this job is that you have to focus on substance and not on social media posts.”
“We’re not going to do things in terms of the rhetoric or hyperbole. We’re going to do things on really practical, calm, steady decision making. Because I think that actually the British character more widely is to do things in a serious and steady way.”
