Iran promises "eternal consequences" after US attack.

Revenge could be taken out on American soldiers in the Middle East.

Or through terror in the United States, American authorities warn.

After the US attack: "We have opened Pandora's box"

US President Donald Trump triumphantly spoke about Saturday night's attack on the Iranian nuclear energy program.

But within his administration, the mood is more tense. The next 48 hours are particularly worrisome, according to sources to NBC News.

Now they are preparing for revenge.

– The US's large number of military bases in the Middle East is not a strength, but a vulnerability, says Iran's Islamic Revolutionary Guard Corps, according to the IRNA news agency.

Iranian President Masoud Pezeshkian says the country has been subjected to"military aggression" and that revenge is to be expected.

"Our nation will never give in to bullying and oppression, and it is natural that we respond appropriately," he said in a statement on the government's website, according to the BBC.

The US has sent 52 military planes with soldiers and equipment to the Middle East in the past week, according to Sky News.

40,000 soldiers are reportedly stationed at American bases in Iraq, Kuwait, Qatar, Bahrain and the United Arab Emirates, which are now being identified as Iranian targets.

Increased terrorist threat

The US Department of Homeland Security is simultaneously warning of an increased terrorist threat in the United States.

– Law enforcement agencies have thwarted several potentially deadly Iran-backed plots in the United States since 2020, and the ongoing Israel-Iran conflict may motivate violent extremists seeking to attack targets, the agency said, according to CBS News.

The threat will increase even more if Ayatollah Khamenei calls for retaliation against the United States, it is claimed.

“The likelihood that violent extremists in the United States will independently mobilize for violence in response to the conflict would increase”:

The Security Service has no information about an increased terrorist threat against Sweden:

– We are closely following the work of the Security Service and making ongoing assessments. If measures are needed, we will do so, but as far as the here and now is concerned, I have no further information. And I have no information or data about any changes to the terrorist threat level, says press officer Karl Melin.
