Suleiman Abu Ghaith, one of Osama bin Laden’s sons-in-law and a former spokesman for Al Qaeda, heads to trial next week in New York on terror-related charges in a case that could feature testimony from several Al Qaeda figures. Prosecutors have accused Abu Ghaith of conspiring to kill Americans immediately after the deadly 11 September 2001 attacks on the World Trade Center, just blocks away from the federal courthouse where his trial will take place. Specifically, the government contends that Abu Ghaith spent time in Afghanistan with bin Laden shortly after 11 September 2001, and recorded several statements threatening further attacks against Americans. Lawyers for Abu Ghaith have argued in court papers that the government has failed to show that Abu Ghaith was a member of Al Qaeda, that he was aware of any plots against the US or that he was involved in the planning of any attacks.
