STOCKHOLM (AP) – The White House says U.S. President Donald Trump has called Sweden’s prime minister to extend his condolences over the fatal truck attack.

The president’s office says Trump spoke to Prime Minister Stefan Lofven on Sunday “to express condolences to the loved ones of those who were killed in Friday’s terrorist attack in central Stockholm,” adding that he wished “a speedy recovery” to the wounded.

Four people were killed and 15 wounded when a stolen truck crashed into shoppers in Stockholm.

The White House statement, issued Monday, said “the two leaders agreed to maintain and strengthen the already close partnership between the United States and Sweden in the global fight against terrorism.”

In February, Trump surprised Swedes when he suggested that Sweden could be the next European country to suffer the kind of extremist attacks that have hit France, Belgium and Germany.
