Serious incident on London Transport
This is going up live as we get the reports. Keep refreshing for more updates.
By the looks of it, all transport systems in London are down - advice is to not go in if you're not there, and to stay where you are and keep away from windows if you're in already. - OFFICIAL GOVERNMENT WARNING: "People in London do not attempt to move around city, stay where you are. All transport routes are closed, trying to minimise movements of people to avoid chaos. Do not call emergency services unless incident is life threatening."
BBCnews24 reports possible bomb incidents at the following stations:
Aldgate East, but not all of these are necessarily explosions.
Sky says three bus explosions as of now, Mobile networks are DOWN, in order to prevent more bombs being triggered, so advice is not to panic if trying to get through to anyone in London and use their landlines if possible.
Reports on fatalities not consistent yet, but at least one person is in "serious condition".
MORE: Guardian website is also down for the moment, but it is claimed to have quoted eyewitnesses who saw 'bodies, some missing arms and legs' at Tavistock Square, 'bodies everywhere' at Liverpool Street. This has not yet been substantiated as far as I can tell.

Blair has confirmed that these are terrorist attacks, will leave Gleneagles to gain reports, but the summit will continue: TRANSCRIPT FOLLOWS
"It is the will of all the leaders of the G8 that the meetings should continue in my absence.. we should discuss and reach the conclusions we were going to reach. each of the countries around the table have experienced terrorism, so they understand what the UK is going through. It is particularly barbaric that this has happened on a day where peole are meeting to help the problems of poverty in Africa, climate change and the environment. It is clear that is a terrorist attack linked to the opening of the G8. We will talk later about this, it's important however that those engaged in terrorism realise that our determination to defend our values and way of life is greater than their determination to cause death and destruction to innocent people in their desire to impose extremism on the world. It is our determination that it will not succeed, either in this country, or any other civilised country around the world."
