President Trump condemned Thursday’s terror attack in Spain and encouraged its citizens to remain “tough” as the First Lady offered “prayers.”

“The United States condemns the terror attack in Barcelona, Spain, and will do whatever is necessary to help. Be tough & strong, we love you!,” the president posted on Twitter.

About an hour before, First Lady Melania Trump reached out to the Spanish people on Twitter.

“Thoughts and prayers to #Barcelona​,” she wrote.

Secretary of State Rex Tillerson offered condolences to the victims and said the US consulate would be providing assistance to American citizens in Spain.

“We offer our condolences to the loss of life and the injuries that have occurred to so many innocent people yet again,” he said during a press briefing at the State Department.

He also added a warning to those who carried out the deadly attack.

“Terrorists around the world should know the US and its allies will resolve to find you and bring you to justice,” Tillerson said.

Acting Homeland Security Secretary Elaine Duke is also monitoring the situation in Spain and has reached out to authorities there, a statement said.

“We will not let terrorism become the new normal,” the statement said. “Instead, such acts of violence only harden our resolve to fight back against violent extremists, bring them to justice, and dismantle their networks.”

A van mowed down a crowd of pedestrians in a tourist area of Barcelona, killing at least 13 people in what officials are describing as a terror attack, according to reports.
