Celia Larsen visited the embassy with her husband and two young children. She's from Oslo, and as she spoke, tears fell from her eyes.
"It's just sad, really sad," she says. "Ninety young people dying for no reason."
Native Norwegians weren't the only ones paying tribute to the victims.
March Rich, an American, came with her two teenagers.
"It's not just thinking about your own children," she says. "It's not oh this couldn't happen to my kids. It could happen to anybody's kids. This did happen."
Many of those who visited the embassy say they came after today's church services.
