Just turned on the news and there's pictures of this massive explosion at Buncefield oil depot in Hemel Hempstead, in Hertfordshire. The scenes are just unbelievable, with smoke clouds that are covering a large part of the South East. Here's a load of photos on BBC Online.
I just can't believe how many people from so far away heard and felt the blast. Have a look at some of these online discussions.
Simon Bisson has some posts on this, and needless to say, some photos he's taken from his house of the smoke approaching London.
Simon points us to a Flickr group set up for pics of the Hemel Hempstead fire and explosion.
