People across Boston paused for a moment of silence on the second anniversary of the Boston Marathon bombings to remember those who were killed.
Church bells tolled at 2:49 p.m. Wednesday, the time the first bomb went off at the race's finish line.
The observance was a highlight of "One Boston Day." Mayor Marty Walsh declared April 15 a day to show kindness and generosity to honor the bombing victims.
Earlier Wednesday, Walsh, Gov. Charlie Baker and other officials unveiled commemorative banners at the site of the blasts on Boylston Street. The orange banners bear a white heart with a road receding into the distance and the word "Boston."
The four banners were mounted on light poles wrapped in blue and yellow flowers, the marathon's colors.
Jane Richard, who lost a leg in the blasts that took the life of her 8-year-old brother, Martin, helped unveil one set of banners.
Three people were killed and more than 260 others were wounded in the attacks. The surviving bomber, Dzhokhar Tsarnaev, has been convicted of 30 counts during his federal trial and could face the death penalty.
