A decade after two homemade bombs exploded at the finish line of the Boston Marathon, the city will mark the somber occasion Saturday with prayers for those who died and activities demonstrating the community's resilient spirit.

Boston Mayor Michelle Wu, who was making her first run for City Council when the bombing happened, will join families who lost love ones to lay a wreath at memorial sites. A brief ceremony will be held later in the day at the finish line of marathon, where bells will ring followed by a moment of silence.

The 127th running of the Boston Marathon takes place Monday.

“I have since spoken with many, many community members, families who have been forever impacted and who carry that trauma with them to this day," Wu said, recalling how people streamed into her campaign office that day with a sense of “confusion and fear and shock about what was happening.”

“The whole world saw Boston pull together in that moment and, to this day, we still carry that moniker of resilience and strength," she added.

Three people were killed and more than 260 were injured when two pressure-cooker bombs went off at the marathon finish line. Among the dead were Lu Lingzi, a 23-year-old Boston University graduate student from China; Krystle Campbell, a 29-year-old restaurant manager from Medford, Massachusetts; and 8-year-old Martin Richard, who had gone to watch the marathon with his family.

During a tense, four-day manhunt that paralyzed the city, Massachusetts Institute of Technology Police Officer Sean Collier was shot dead in his car. Boston Police Officer Dennis Simmonds also died a year after he was wounded in a confrontation with the bombers.

Police captured a bloodied and wounded Dzhokhar Tsarnaev in the Boston suburb of Watertown, where he was hiding in a boat parked in a backyard, hours after his brother died. Tamerlan Tsarnaev, 26, had been in a gunfight with police and was run over by his brother as he fled.

“I think we’re all still living with those tragic days 10 years ago," Bill Evans, the former Boston Police Commissioner, said.

Dzhokhar Tsarnaev was sentenced to death and much of the attention, in recent years, has been around his bid to avoid being executed.

A federal appeals court is considering Tsarnaev’s latest bid to avoid execution. A three-judge panel of the 1st U.S. Circuit Court of Appeals in Boston heard arguments in January in the 29-year-old’s case, but has yet to issue a ruling.

The appeals court initially threw out Tsarnaev’s death sentence in 2020, saying the trial judge did not adequately screen jurors for potential biases. But the U.S. Supreme Court revived it last year.

The 1st Circuit is now weighing whether other issues that weren’t considered by the Supreme Court require the death sentence to be tossed a second time. Among other things, Tsarnaev says the trial judge wrongly denied his challenge of two jurors who defense attorneys say lied during jury selection questioning.

The bombing not only unified Boston — “Boston Strong” became the city’s rallying cry — but inspired many in the running community and prompted scores of those impacted by the terror attack to run the marathon.

“It really galvanized and showed our sport’s and our city’s resiliency, our desire together to continue even better and to enhance the Boston Marathon,” Boston Athletic Association President and CEO Jack Fleming said. "The bombing in 2013 resulted in a new appreciation or a different appreciation for what Boston, what the Boston Marathon, has always stood for, which is that expression of freedom that you receive and get while running.”

On Saturday, the focus will mostly be on remembering victims and survivors of the bombing but also, as Wu said, “really making sure this was a moment to focus on where the city and our communities, our families are headed in the future.”

That sentiment will be reflected in what has become known as “One Boston Day,” where acts of kindness and service take place to honor victims, survivors and first responders. This year, nearly two dozen community service projects are happening including a shoe drive and several food drives, blood drives and neighborhood cleanups.

“This time of year evokes a strong emotion for so many of us across the City and the people touched by the tragedy ten years ago. But the most prevailing one is that Boston is indeed strong, and that our communities show up for each other in times of need,” Jacob Robinson, the executive director of West Roxbury Main Streets, one of the groups hosting the shoe drive, said in a statement.

NASHVILLE, Tenn. — AT&T said crews have made significant progress restoring service to the region on Sunday morning following an explosion on Friday morning outside an AT&T data center.

The explosion impacted widespread service interruption reaching outside of just Middle Tennessee.

On Sunday morning, the company said power has been restored to four floors of the building and more than 65% of mobile sites affected by the explosion have been restored.

More than three feet of water was pumped out of the building's basement on Saturday, however, access to some of the lowers is still limited.

AT&T said on Sunday crews will be adding additional cabling and more generators to provide more power into the building to help with restoration efforts.

"Teams are working to safely bring additional equipment online and reroute services through other facilities in the region. While mobility services have been restored in many areas, we still have more than 17 portable cell sites on the air to aid in communication, including for restoration teams and first responders," AT&T said in an update. "We are bringing in additional resources to support the recovery of wireline voice and data services and expect to have a fleet of 24 additional trailers of disaster recovery equipment on-site by the end of the day."

The company did not provide an exact time when it expects service to fully be restored. Metro officials said there will be times customers will lose service as restoration efforts continue but officials are confident to be running at full capacity by the end of Sunday.

Damage to the building is still being assessed.
