HELSINKI -- Swedes have been scratching their heads and ridiculing President Donald Trump’s remarks that suggested a major incident had happened in the Scandinavian country.

During a rally in Florida on Saturday, Mr. Trump said “look what’s happening last night in Sweden” as he alluded to past terror attacks in Europe. It wasn’t clear what he was referring to and there were no high-profile situations reported in Sweden on Friday night.

The comment prompted a barrage of social media reaction on Sunday, with hundreds of tweets, and a local newspaper published a list of events that happened on Friday that appeared to have no connections to any terror-like activity. The hashtags #lastnightinsweden and #swedenincident began trending on Twitter.

Foreign Ministry spokeswoman Catarina Axelsson said that the government wasn’t aware of any “terror-linked major incidents.” Sweden’s Security Police said it had no reason to change the terror threat level.

“Nothing has occurred which would cause us to raise that level,” agency spokesman Karl Melin said.

In a tweet late Sunday afternoon, Mr. Trump attempted to clarify his comment:

My statement as to what's happening in Sweden was in reference to a story that was broadcast on @FoxNews concerning immigrants & Sweden. — Donald J. Trump (@realDonaldTrump) February 19, 2017

But the president’s comments had Swedes confused and amused. Former Swedish Foreign Minister Carl Bildt tweeted , “Sweden? Terror attack? What has he been smoking? Questions abound.”

Addressing Mr. Trump in an article on Sunday, the Aftonbladet tabloid wrote, “This happened in Sweden Friday night, Mr President,” and then listed in English some events that included a man being treated for severe burns, an avalanche warning and police chasing a drunken driver.

One Twitter user said, “After the terrible events #lastnightinSweden, IKEA have sold out of this” and posted a mock Ikea instruction manual on how to build a “Border Wall.”

Sweden, which has a long reputation for welcoming refugees and migrants, had a record 163,000 asylum applications in 2015. The country has since cut back on the number it annually accepts.

Its most recent attack linked to extremism happened in the capital, Stockholm, in December 2010. An Iraqi-born Swede detonated two explosive devices, including one that killed him but no one else.

At the rally, Mr. Trump told his followers to look at what was happening in Germany, where a truck attack at a Berlin Christmas market killed 12 people. He also mentioned Paris, Brussels and Nice, in apparent reference to the terror attacks there.

The president didn’t specify what was supposed to have happened in Sweden, simply saying “Sweden, who would believe this, Sweden.”

Former foreign minister Bildt told Swedish Radio after his initial confounded tweet Sunday that he sees danger in how Mr. Trump relates to facts.

“If we are in a situation where there is tension in the world, we stand between war and peace,” he said. “If we then have a president who spreads lots of false rumors, it can be truly dangerous.”

Earlier this month, Mr. Trump’s adviser Kellyanne Conway alluded to “the Bowling Green Massacre” - an event that never happened – in an effort to defend the administration’s travel ban.
