London terrorist plot foiled” target=”_blank”> London Dirty Bomb Attack Foiled:

LONDON, Aug. 21 (UPI) — The Times of London has obtained an internal British document that shows police thwarted a plot to hit targets with chemicals, sarin gas or a dirty bomb.
A dirty bomb is a conventional explosive wrapped in radioactive material.
One of the targets was the House of Commons, the document revealed.
Government officials have confirmed the report, the Times said.
The al-Qaida plot is believed to have been discovered in computers and emails seized from suspected terrorists in Britain and Pakistan, the newspaper said.
Using the information police were able to identify the al-Qaida cell.
This summer security at the House of Commons building was stepped up because of the plot.
A recent security sweep revealed that the Parliament building is still vulnerable to attacks.
