A Pakistani-origin taxi driver indicted on charges of providing material support to terror group al-Qaeda and accused of having links with HuJI chief Ilyas Kashmiri pleaded not guilty in a US court. Wearing an orange prison jumpsuit with his hands shackled, 56-year-old Raja Lahrasib Khan appeared before Judge James Zagel in US District Court Chicago for his arraignment. After taking an oath, Khan said he is pleading not guilty to the charges of providing material support and funds to Osama bin Laden's terror group. During short session, the Judge set May 5 as the date for next hearing. His arrest comes five months after Chicago residents David Headley and Tahawwur Hussain Rana were arrested by the FBI on terror charges. Headley has since pleaded guilty to his role in the Mumbai 26/11 attacks.
