The BBC, Sky News and other British media outlets are describing this morning's transit blasts as "minor." About an hour ago, Prime Minister Tony Blair told reporters there were "zero" casualties, but press reports indicate there were injuries.
My first reaction is that today's attacks appear hastily planned and executed, a sharp contrast to the attacks of 7/7. The bombs may be similar to those used two weeks ago, but they inflicted less damage and casualties. British police reportedly arrested a number of suspects immediately after the attacks. With British authorities hot on the trail of London's Al-Qaida affiliate, today's strike may have been an effort to inflict more damage before police put the bombers completely out of business.
