A wreath was laid at the finish line of the Boston Marathon this Sunday morning to mark the anniversary of the deadly bombing five years ago.
Boston Mayor Marty Walsh and Governor Charlie Baker participated in the ceremony.
There will also be a moment of silence at 2:49 pm Eastern, when the first explosion took place.
On April 15, 2013, three people were killed and more than 260 injured when two bombs exploded near the finish line of the race.
The bombs were made out of pressure cookers, packed with bb-like pellets and nails.
Authorities identified the bombers as brothers Tamerlan Tsarnaev and Dzhokhar Tsarnaev, who were originally from Chechnya.
Tamerlan was killed in an encounter with police three days after the bombing.
Dzhokhar was convicted of involvement and given the death sentence.
He is being held in a supermax prison in Florence, Colorado.
