Jurors retired for an 11th day yesterday to consider their verdicts in the year-long fertiliser bomb plot trial at the Old Bailey.

Seven British men 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 say they did not know what the fertiliser was, they were only interested in sending supplies to fighters in Kashmir and Afghanistan or they were duped.

Four men from Crawley, West Sussex, - Omar Khyam, 25, his brother Shujah Mahmood, 20, Waheed Mahmood, 35, and Jawad Akbar, 23, - deny a charge of conspiring to cause explosions likely to endanger life between January 1, 2003, and March 31, 2004.

Anthony Garcia, 25, of Barkingside, east London, Nabeel Hussain, 21, of Horley, Surrey, and Salahuddin Amin, 32, of Luton, Bedfordshire, also deny the charge.

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.
