BuzzMachine has a round-up of links to London blogs. Barcepundit’s posting (in Spanish) from London. Hispalibertas is also posting in Spanish.

The Corner is updating constantly. Cliff May: “It would be a useful advance if it were widely understood that those created this carnage are to blame for this carnage – and no one else.”

Update (continued) Rachel is liveblogging.
Is there still a Britain? We’re about to find out.
The Secret Organisation of al-Qaida in Europe has posted a claim of responsibility Chrenkoff notices the hour of the first attack.

It takes a certain brand of perverse degeneracy to be a terrorist.

Update 2 Michelle is updating, too. La Shawn points out “The cowards in dirty nightshirts say they’ve killed Egypt’s Iraq envoy, whom they kidnapped a few days ago.”

As for “we’re all Britons today”, as I commented at Roger L. Simon’s, Yes, in a sense we’re all Britons now, in that we all grieve together for the victims.
However, back in 2001 I found Colombani’s (editor of Le Monde) We Are All Americans insulting and offensive, in that the article’s tone was one of “yes, we’re all Americans, and we’re to blame” and I quote,

But the reality is perhaps also that of an America whose own cynicism has caught up with. If Bin Laden, as the American authorities seem to think, really is the one who ordered the Sept. 11 attacks, how can we fail to recall that he was in fact trained by the CIA and that he was an element of a policy, directed against the Soviets, that the Americans considered to be wise? Might it not then have been America itself that created this demon?

As Captain’s Quarters (who has a post titled We’re All Britons Today) states,

AQ does not exist because of Bush or Blair. AQ has attacked Western interests since at least 1993 because of who we are and what we represent. They have no ideology except that of hatred for freedom and the imposition of Taliban-like tyranny across Southwest Asia and eventually the world. Everywhere they have ruled, such as Afghanistan, Fallujah, Ramadi, Qaim, and other areas, they have brutally suppressed freedom of expression and civil rights.

Ignoring them does not work. Sympathizing with them encourages their bloody attacks. Disarming ourselves in the face of their attacks only confirms our weakness and stokes their apocalyptic dreams. Just as with other lunatic vanguards of fascism, the only option that will put an end to their deadly efforts is to crush them and to spread freedom and democracy to completely discredit their despotic philosophies.
