Update at 9:36 a.m. ET: In Newtown and across the nation, bells rang starting at 9:30 a.m. ET, to honor the 20 children and six adults killed one week ago at Sandy Hook Elementary School in Newtown, Conn. And on the Web, it appears many did take part in #MomentForSandyHook — judging from the sharp slowdown in our Twitter feed.

As church bells ring at 9:30 a.m. ET today in Newtown, Conn., many across the nation will pause to remember those killed one week ago.
It was about that time last Friday, authorities say, when gunman Adam Lanza entered Sandy Hook Elementary School. Before taking his own life, he fatally wounded 20 first-graders and six adults.
One way to participate in the moment will be to step away from your computer, tablet or smartphone. It's being called #MomentForSandyHook. The idea is to disconnect for five minutes.

I know that for many of you, the pain you are enduring right now seems unbearable; and many of you may be asking yourselves, how can we go on — as families and as a community? But I also know that we have already begun to see the answer to that question in the countless acts of courage, kindness and love here in Newtown and across America."
