London Terrorist Attacks

Dozens are reported dead, and hundreds are injured in an apparent coordinated terrorist attack in London, with several blasts occurring in Underground subway stations and on a double-decker bus.

Seven explosions occurred, starting at 8:50 a.m. local time, at financial district Underground stations, including Liverpool Street, Moorgate and Aldgate East, police said. Casualties were on a bus that exploded near Russell Square, a firefighter said. Nobody claimed responsibility for the attacks, which come a day after London was awarded the 2012 Olympics.

The website of a group entitled "Secret Organisation - al-Qaeda in Europe" has claimed responsibility with the attacks, which coincided with the G8 economic summit taking place in Scotland.  The self-declared culprits threatened similar attacks on Italy, Denmark, and other "crusader governments" with troops in Iraq and Afghanistan.  Der Spiegel Online has a screenshot of the letter claiming responsibility (HT: MM).

From Tony Blair's second address since the attacks, at 8:10 am Eastern:

We condemn utterly these barbaric attacks.  We send our condolences to the victims and their families ...  [This is an] attack not on one nation, but on all nations, and on civilized people everywhere.  We will not allow violence to change our values, nor we will allow it to stop our deliberations. The perpetrators of these attacks are intent on destroying human life ... We shall prevail and they shall not.

Instapundit and Michelle Malkin have ongoing roundups.

As of 8:25, international markets were reacting negatively:

      Nikkei  -0.12%    -13.39    11,590.14

In the U.S. Dow futures were down 136, Nasdaq futures were down 22.00, and S&P futures were down 14.9, before the market opened.

From remarks made earlier by London's mayor Ken Livingstone, directed toward the terrorists responsible for the attacks:

I know that you personally do not fear to give your own life ..., but I know that you do fear that you may fail in your long term objective, and I will show you why you will fail.  In the days that follow ... people from around the world will arrive in London ... as so many have chosen to come before.  Whatever you do, however many you kill, you will fail.
