President Obama marked the anniversary of the Boston Marathon bombings on Tuesday by praising those who helped in the wake of the chaos. 

"We also know that the most vivid images from that day were not of smoke and chaos, but of compassion, kindness and strength: A man in a cowboy hat helping a wounded stranger out of harm’s way; runners embracing loved ones, and each other; an EMT carrying a spectator to safety," Obama said in a statement.


Obama remembered the three people who died after the two explosions, the hundreds who were injured by the blasts and the first responders and spectators who came to their aid. He also spoke of the MIT police officer who was killed days later in a manhunt.

The White House is scheduled to hold a moment of silence for the victims of the attack at 2:40 p.m. on Tuesday. Vice President Biden is traveling to Boston to give remarks at noon. 

When the marathon takes place next Monday, Obama said, the city will show the world "the meaning of Boston Strong as a city chooses to run again."

"One year later, we also stand in awe of the men and women who continue to inspire us — learning to stand, walk, dance and run again," he said in the statement. "With each new step our country is moved by the resilience of a community and a city."

The Boston attack in April 2013 eventually led to the arrest of Dzhokhar Tsarnaev and the death of his brother, Tamerlan Tsarnaev. A MIT police officer, Sean Collier, was also killed during the manhunt for the two bombers. 

The three people who died during the bombings were Krystle Campbell, Lingzi Lu and Martin Richard.
