President Donald Trump is seen during a campaign rally at the AeroMod International hangar at Orlando Melbourne International Airport on February 18, 2017 in Melbourne, Florida.

After bewildering residents and officials of Sweden by suggesting Saturday that a terror-related incident had occurred over the weekend in the small Nordic nation, President Donald Trump attributed his comment to a Fox News interview with a conservative filmmaker.

"We'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," Trump told the crowd at his campaign-like rally in Florida on Saturday, critiquing Europe's refugee policies and complaining that his travel ban had suffered setbacks in court. "Sweden, who would believe this?"

It was unclear following the rally what could have occurred in Sweden to draw the president's attention, and the Swedish Embassy asked for clarity.

Trump took to his Twitter account Sunday evening to explain that he was referring to a Tucker Carlson segment that appeared on Fox News Friday. In the segment, Carlson interviewed right-wing filmmaker Ami Horowitz, who had recently made a documentary about Sweden's refugee policy. The segment did not contain breaking news.

A spokesperson for the Swedish Embassy said they didn't know if Trump's tweet served as the government's official response to their request for an explanation.

"We have asked State Department if President Trumps' tweet is their official answer to our question earlier today. We are still awaiting an answer on that," the spokesperson said.

A White House spokesperson had attempted to explain what Trump had been referring to prior to Trump's tweet.
