Jurors have retired for a ninth day in the yearlong fertiliser bomb plot trial at the Old Bailey.

Seven British men, including four from Crawley, were arrested in March 2004 following the discovery of more than half a ton of chemical fertiliser in storage in west London.

The prosecution alleges they were involved in a plot to bomb targets in Britain, including the Bluewater shopping centre in Kent and the Ministry of Sound nightclub in London, and to hit gas and electricity supplies.

The defendants deny there was a plot.

Omar Khyam, 25, his brother Shujah Mahmood, 20, Waheed Mahmood, 35, and Jawad Akbar, 23, all from Crawley, Anthony Garcia, 25, of Barkingside, east London, Nabeel Hussain, 21, of Horley, Surrey, and Salahuddin Amin, 32, of Luton, Bedfordshire, deny conspiring to cause explosions likely to endanger life between January 1, 2003 and March 31, 2004.

Khyam, Garcia and Hussain also deny a charge under the Terrorism Act of possessing 1,300lb (600kg) of ammonium nitrate fertiliser for terrorism.

Khyam and Shujah Mahmood deny possessing aluminium powder for terrorism.
