Katy Perry, Coldplay, and Rob Lowe are among the stars who have reached out to the people of Norway following a killing spree at a youth camp and a deadly bombing in the capital.
At least seven people died after an explosion ripped through Oslo on Friday, blasting buildings in the city's government quarter. Just hours later, a gunman dressed as a police officer opened fire at an island summer camp for teens, killing as many as 84 people, including several youngsters.
Celebrities were quick to react to the news, taking to their blogs on Twitter to express their devastation and send sympathies to Norwegian residents.
In a post on her Twitter, Perry writes, "Let's pray for our Norway friends as we lay our heads down tonight!"
British rockers Coldplay also remarked on the tragedy, tweeting: "Our love goes out to the people of Norway. What a monstrous thing to happen to such a beautiful country and people."
Singer Josh Groban adds, "Watching the horrible news about what happened in my beloved Norway. Such shocking attacks, sending love to everyone there," while Boy George writes, "Today is the saddest day for the people of Norway, I cannot comprehend the crime, my prayers are with you all! Shocking!"
Lowe told fans, "My thoughts and prayers are with the people of Norway today," as fellow actor Danny Masterson shared, "Send your prayers to Oslo Norway everyone. Disgusting act of violence committed today. Norway is an amazing country."
Punk icon Henry Rollins paid tribute to the spirit of Norway's citizens, writing, "Been to Norway many times. Awful what happened. A very peaceful place and people," and a stunned Patricia Heaton added, "I can't get my head around the massacre in Norway. That one person can cause such senseless destruction. Pray for the parents of these kids."
"One Tree Hill" star Sophia Bush wrote, "Terrible news about the bombing in #Oslo #Norway today. You are all in my thoughts…"
Our thoughts and prayers go out to Norway and all the families and friends who lost loved ones.
