Citizens gathered in Albert Square outside Manchester's Town Hall and waved “I Heart Manchester” signs as Lord Mayor Eddy Newman spoke at a vigil honoring the 22 victims who perished and the 59 who were injured.

“The people of Manchester will remember the victims forever and we will defy the terrorists by working together to create cohesive, diverse communities that are stronger together,” he said. “We are the many, they are the few.”

Pink balloons, which cascaded across the audience at Grande’s concert Monday night as part of the show, have become a symbol of remembrance.

The city released 22 pink balloons, one for each of the victims, at the poignant vigil Tuesday.

Police raided the home of terrorist Salman Abedi Tuesday. The 22-year-old was born in Manchester and is of Libyan descent. He was said to be on the radar of British authorities as a potential ISIS recruit and he recently visited Syria.

During the raid, authorities took away computers and a book titled: Know Your Chemicals. They also arrested Abedi's older brother and two others.

British Prime Minister Theresa May raised the threat level to critical and warned of more attacks to come.

“Not only does an attack remain highly likely, but that a further attack may be imminent,” she said.

In New York City, the British national anthem, “God Save the Queen” was played before Tuesday night's Yankees game, one of many acts of solidarity around the world.

On The Voice finale, Miley Cyrus dedicated a song to the victims of the attack.

“I would like to dedicate this song to my friend Ariana Grande,” the singer said. “And all those who experienced the attack in Manchester, our hearts are with you.”

Appearing on Jimmy Kimmel Live Tuesday night, U2’s Bono addressed the attacks and denounced the constant terror of ISIS in the Western World.

“They hate music. They hate women. They even hate little girls. They hate everything that we love,” the Irish rocker said. “The worst of humanity was on view in Manchester last night, but so was the best as people took perfect strangers into their houses and queued up at blood banks. Manchester has an undefeatable spirit, I can assure you.”

There is a heightened state of alert at concerts and sporting events. Security was stepped up at Tuesday night's NBA playoff game at Quicken Loans Arena in Cleveland, Ohio as the hometown Cavs took on the Boston Celtics.
