Reports of more bombs in London. What the hell is going on? My sister, who was caught in the middle of London again, has phoned to say it is like living in hell - with police sirens as a constant back drop to her call as she once again has to walk several miles home as the transport network grinds to a halt. To keep up to date on just what madness has happened this time, check out the bbc news website, or the Guardian site, particulalry the news blogs.

Really depressing news, no matter what the extent of today’s attacks turns out to be.
