Washington, Apr 16 (IANS): Boston on Saturday marked the third anniversary of the deadly marathon bombings on April 15, 2013.

Church bells rang throughout the city as residents bowed their heads for the moment of silence at 2.49 p.m. on Friday, three years after the first of two bombs went off near the Boston Marathon finish line, CBS Boston reported.

Earlier in the day, the city marked the anniversary with a wreath laying ceremony.

Boston Mayor Marty Walsh led the ceremony outside of Marathon Sports while Governor Charlie Baker laid a wreath near old Forum Restaurant.

With bagpipes playing "Amazing Grace", Walsh stepped aside to allow eight-year-old Martin Richard’s father Bill to place the wreath along with a relative of Lingzi Lu.

Baker was joined by Krystle Campbell’s father to lay the wreath outside Forum, which has since closed.

Richard, Lu, and Campbell were killed in the bombings. Police Officer Sean Collier was killed during the manhunt for the suspects four days later.

Crosses with pictures of each victim were placed on a tree in the area.

The ceremony was a part of One Boston Day, which Mayor Marty Walsh proclaimed will take place annually on April 15.

One Boston Day “encourages random acts of kinds and spreading of goodwill” in an effort to give back to the community that was unified in the aftermath of the bombings.
