PHILADELPHIA (CBS) — As the world mourns for those affected by the attack in Manchester, England, people in the Philadelphia area are remembering the victims.

In Philadelphia, supporters of rival Manchester soccer teams gathered to honor the bombing victims with a moment of silence, and holding a vigil outside of City Hall early Tuesday evening.

Monday night’s terror attack at Manchester Arena following the Ariana Grande concert killed 22 and left dozens of others injured.

The Islamic State of Iraq and Syria claimed responsibility for the attack.

And although, Manchester City and Manchester United are sworn enemies. In moments like this, everyone is on the same squad.

“They’ve been so great to me, Mancunians, I had to do something,” said Chrissy Rockwell.

Rockwell is part of Man City fan page on Facebook, and organized Tuesday’s vigil.

“I knew that as soon as I put something up, I’d be able to get people out,” she said.

So she reached out to bring everyone together.

“I was on Twitter as it happened. You know, half of my friends list is Philly, half my friends list is Manchester. As it’s going on, I saw it. It’s something that really affected me and I just felt like I had to do something,” said Rockwell.

Declan Ware also grew up in Manchester and now lives in Philadelphia.

“I’ve always found this city very welcoming” he said. “The City of Brotherly Love for a reason.”

He’s blown away the compassion his new neighbors have shown.

“It’s so nice to have people express their support and their sorrow,” said Ware.

And then he was holding back the tears when talking about how his hometown will overcome this

“It also makes you feel proud to be associated with that city and they way people have come together in the way they have,” he said. “It’s heartwarming.”

The vigil was a way to honor those involved in the terror attack and give people in the area a way to grieve.
