The former Swedish foreign minister wondered what Donald Trump was “smoking” after the president referred to a nonexistent terror attack in the Scandinavian country.

“Sweden? Terror attack? What has he been smoking? Questions abound,” a baffled Carl Bildt tweeted late Saturday about Trump’s comments during a rally in Florida earlier in the day.

Defending his immigration ban, Trump recounted terror attacks in Brussels, Nice and Paris – and then lumped in Sweden.

“You’ve got to keep our country safe. You look at what’s happening in Germany, you look at what’s happening last night in Sweden,” he said during the speech in Melbourne, Fla.

“Sweden, who would believe this? Sweden?” Trump continued. “They took in large numbers. They’re having problems like they never thought possible.”

The Swedish embassy on Sunday said it had reached out to the state department “to get clarity.”

Later, the White House said the president was talking about “rising crime and recent incidents, in general,” not “a specific incident.”

Trump may have conflated the notion of Sweden and terror from a Tucker Carlson interview on Fox News Friday night with a journalist who said there had been an increase in “gun violence and rape” in Sweden since the European migrant crisis began.

The Swedish newspaper Aftonbladet took a lighter approach to the non-existant attack by listing a number of news events that happened in the country on Friday — including a man severely burned, an avalanche warning and a police chase involving a drunken driver — but no terrorism.
