Just in case you haven't turned on the TV or radio yet, there was an explosion - highly likely to be accidental - at an oil depot near Hemel Hempstead, north of north London in Hertfordshire at 6am this morning. Absolutely nothing to do with London Underground or the Tube, but maybe Watford, Chorleywood or Chalfont & Latimer may use it as an lame excuse to close because of the visibility! Smoke from the fire could actually be seen from many areas in London.
People as far south as Holland are said to have heard the explosion which has led to one of the biggest fires the UK has seen in 10 years. Check out the Flickr for pictures tagged Buncefield and Technorati too.
Thanks to Ken Douglas for the excellent title for this post and some impressive photos. Fortunately there have been no fatalities and amazingly only 36 injuries.
