Triple Nine Bombing

On the 9th of September, 2009, a terrorist dirty bomb was detonated on a Tube train in West London, killing 189 people and contaminating a significant portion of London with radioactive material. It was the worst terrorist attack in the UK by far.

Incident:
At 9:07am on the morning of September 9th, 2009, an improvised radiological dispersal device or 'dirty bomb' was detonated on a Tube train at Knightsbridge station. The dirty bomb was hidden in a rolling suitcase, and contained 12 kilograms of cobalt-60 and 28 of Semtex, designed for maximum casualties and panic. Only a fraction of the 189 people were killed by the explosion, the rest inhaled cobalt-60 dust for multiple minutes before escaping, causing scores of cases of radiation poisoning; the majority of which were fatal. The suction of a passing train less than a minute later drew the cobalt-60 dust hanging in the air out into the open air above the station, contaminated a portion of London now known as the Radiation No-Go Zone (RNZ).

Subsequent investigation showed that the suicide bomber had intended to detonate the bomb further down the line, with the intent of contaminating Buckingham Palace with the fallout, but unknown circumstances caused him to detonate early. Only the Mossad knew that this was because the bomber had identified one of their Kidon 11 operatives, who were on the train to assassinate him, causing him to panic and trigger the device early.

Confirmed casualties:

 * Olivya Lawrence
 * Reginald Lawrence
 * Michael Gallagher
 * Cathy Wainwright
 * Entirety of Mossad Kidon 11
