It appears that up to seven Underground (London's subway system) stops were targeted. Casualties galore (at least 90 reported at one station alone with two fatalities reported). This is all very preliminary but it's obviously an orchestrated attack. Some of the stops included Liverpool, Aldgate, and Kings Cross. There are reports of people still trapped in the Tube and the national morning news shows keep showing looped footage of survivors receiving assistance.
Footage has also been shown of the top of one of London's famous double-decker buses having been destroyed by an explosion.
Now, whether the attack was timed to coincide with the opening of the G8 today or whether Paris, London, Madrid, NYC, etc. were going to be hit one day after the announcement of the location of the 2012 Olympics is also unclear.
What is clear, though, is that the fvcking BS rhetoric from this admin that "America and the world are safer" is now completely and utterly without basis. Attacks like this will continue no matter what countries are invaded and no matter what sanctions are imposed upon others. There will always be a fringe element seeking to cause death and destruction.
Better security at home at ports, chemical plants, transportation hubs, trucking industry, etc. is what we need, not more bombs and bullets.
Here's an early report from CNN:
