NEW YORK- A US prosecutor asked a jury on Wednesday to find a Saudi man guilty of conspiring with al Qaeda in the 1990s when he allegedly managed a training camp in Afghanistan and then served as Osama bin Laden's agent in London.Near the end of a month-long trial of Khalid al-Fawwaz, Assistant US Attorney Sean Buckley told jurors in a closing argument that they had seen enough evidence to convict al-Fawwaz of four terrorism counts."Khalid al-Fawwaz did everything that al Qaeda asked of him," Buckley said in Manhattan federal court. As al-Fawwaz looked on, Buckley called him bin Laden's "man in London."The charges include participating in al Qaeda's years-long conspiracy to kill Americans.Al-Fawwaz is not charged with any killings, but prosecutors say he provided crucial support that laid the groundwork for attacks such as the 1998 bombings at the US embassies in Kenya and Tanzania. Those bombings killed 224 people and wounded thousands more.
