Even living here in Sweden, almost all the front pages of the newspapers are images about September 11. At 1 in the afternoon, they played a memorial ceremony on TV, and there was an official 1 minute of silence.
Venerable Caine Das of Reflection of a Buddhist Monk reflects on the event, entitled September 11, 2011. He also includes an interesting link to a study done by Brown University and the Watson Institute for International Studies, about the effects of this event, 10 years later. The death tolls and monetary costs of the event, and from the wars that followed it are quite shocking.
