Church bells tolled 26 times at St. Rose of Lima church in Newtown Saturday morning to honor the 20 children and six educators who were killed.
The church was just one of several houses of worship that held private services for a community still in mourning.
President Barack Obama said in a radio address that the massacre will be remembered as a tragedy that inspired the nation to make communities safer.
“We have to do more to keep dangerous people from getting their hands on a gun so easily. We have to do more to heal troubled minds. We have to do everything we can to protect our children from harm and make them feel loved, and valued, and cared for,” said Obama, who also observed a moment of silence and lit candles at the White House in honor of the victims.
