WASHINGTON - The US govt completed its evidence on Wednesday in the case of Syed Haris Ahmed, an American citizen of Pakistani origin, who prosecutors allege was a supporter of terrorism, according to media reports from Atlanta, Georgia. The FBI claims Haris Ahmed, a former mechanical engineering student at Georgia Tech, took casing video of the Pentagon and discussed attacks on the US. He was arrested on March 23, 2006 and is being held by the FBI at a facility in Roswell City, Georgia. Police and FBI agents searched the familys home in Dawsonville, where they confiscated computer discs and copied Ahmeds computer hard drive. The trial of Syed Haris Ahmed started Monday. Ahmed, 24, and alleged co-conspirator Ehsanul Islam Sadequee, a US citizen of Bangladeshi descent, are charged with providing material support to terrorists and other conspiracy counts. Sadequee is expected to go on trial in August. Ahmed was told after being interviewed by the FBI not to talk with Sadequee, prosecutors said. But while under FBI surveillance, Ahmed contacted Sadequee, according to prosecutors. Special Agent Matthew Acker testified he watched Ahmed access a computer at a north Georgia library on March 21, 2006. Checking the browser history on the computer, investigators found Ahmed used a Yahoo e-mail account to get in touch with Sadequee, who was visiting his father in Bangladesh. Ahmed and Sadequee took a trip in March 2005 to Canada, where they met three other men and discussed potential targets to attack that include oil refineries, a military base and a GPS satellite system, prosecutors claim. Assistant US Attorney Robert McBurney said Ahmed and Sadequee also travelled to Washington in April 2005 and made shaky 'casing videos of area landmarks including the Capitol, World Bank building and a Masonic Temple. The videos were found on the hard drives of Younis Tsouli and Aabid Hussein Khan after the men were arrested on terrorism charges in the UK authorities said. The govt said both men were in possession of a large quantity of 'violent jihad materials. A terrorism consultant testified Khan and Tsouli had connections with terrorist organisations. Prosecutors said they have resented communication evidence between Ahmed and Khan as well as Sadequee and Tsouli. The govt maintains Ahmeds intentions were to enter a terrorist training camp during a trip to Pakistan in July of 2005. But Defence Attorney Jack Martin said while in Pakistan, Ahmed was talked out of attending a camp by his family. 'I talked to my cousins, and they put some sense into me, Ahmed can be heard saying on a recording during an interview by the FBI. Martin has argued his client is a shy, highly emotional young man. Martin said Ahmed moved to a suburban Atlanta neighborhood with his family when he was 12. He did not have a religious mentor and turned to the Internet to find his identity as a Muslim, Martin said. There never were any agreements established with co-conspirators, and the actions of Ahmed were nothing more than 'childish fantasies, Martin said. Martin said Ahmed did not believe the Yahoo e-mail account was being monitored by the FBI, and pointed out that in a March 21, 2006, e-mail Ahmed wrote to Sadequee: 'I told them (the FBI), which is true to the best of my knowledge, that we were kids who just got excited. Ahmed waived his right to a jury trial and agreed to allow US District Judge William Duffey decide his case. Martin is expected to call two of Ahmeds family members to the stand for the defence later this week.
