From President Obama: "I wanted to personally extend my condolences to the people of Norway. And it's a reminder that the entire international community has a stake in preventing this kind of terror from occurring. And so we have to work cooperatively together both on intelligence and in terms of prevention of these kinds of horrible attacks.
"I remember fondly my visit to Oslo and how warmly the people of Norway treated me. And so our hearts go out to them, and we'll provide any support we can to them as they investigate these occurrences."
