A British man who trained to be a shoe bomber said Osama bin Laden told him shortly after the September 11 2001 attacks that he believed a follow-up terrorist attack could doom the American economy.

A US man accused of becoming an al-Qaida agent discussed bombing New York cinemas, Grand Central Terminal, Times Square and the Stock Exchange before settling on the city’s subways, a court heard today.
