In many ways the attacks virtually mirrored those in Madrid on March 11 2004.
Once again it was the transport network that was targeted and once again the bombs went off almost simultaneously, causing maximum panic and chaos.
One woman in Madrid said she thought London was targeted because it was one of the few major cities linked to the war in Iraq not have been hit by a terrorist attack. “But every country in Europe is scared,” she said, adding: “Even me here in Madrid, I am scared. Every time I take the bus I think it could happen again.”
Meanwhile, Italy’s interior minister said all of Europe had raised its alert level. US ally Rome has some 3,000 troops in Iraq and the group claiming responsibility for the carnage in London has suggested Italy could be next.
The French prime minister has put the country on its second highest level of alert.
Russia is boosting security across the country and the Netherlands is stepping up border checks and increasing police numbers around British buildings.
