ETA terror returns

The Basque separatist group ETA set off 5 bombs around Madrid on Friday. Juan Cole finds it curious that the bombings have received so little attention in the media:

If these bombings had been carried out by al-Qaeda, it would be front-page news and something of concern to Washington.

That it isn't raises the question of anti-Muslimism. Is the difference in the way that the American press responds to ETA from the way it responds to al-Qaeda a form of racism?
