Since the London bombings there have been enormous improvements in the way the police, the security service, community leaders and the public all tackle the threat from international terrorism.

The authorities believe that it would be far harder, in 2015, for terrorists to carry out a complex, co-ordinated bomb plot like 7/7 without being detected. But conversely, that threat has diversified into something far harder to detect and stop.

Anish emails: I saw the bus explode on Tavistock square. The train came to a halt and we were told to make our own way to our destination. I tried to walk to Kings Cross but an area around it had been cordoned off. I still remember how loud the sound was, and how high the top of the bus flew into air. I was 17 - the age when you start to learn some hard truths about the world. You realise that nobody is ever fully in control. We are all in a driverless car and anything can happen to anyone at anytime. I haven't sought any help and do not know whether I have any lasting psychological damage but I read the obituaries of all the victims. I can't think why it didn't occur to me to do before. As a Londoner these people feel so familiar and recognisable to me.

The headline in Spain's El Pais refers to London, external "remembering the victims of the attack that changed the country".
