A Libyan charged in the deadly 1998 al-Qaida bombings of U.S. embassies in Africa pleaded not guilty Tuesday to terrorism charges in a brief proceeding that followed a familiar script in a courthouse that has hosted numerous terrorism cases in the past two decades.

A frail looking Abu Anas al-Libi entered the plea in a heavily guarded federal courtroom in Manhattan 10 days after he was captured during an Oct. 5 military raid in Libya. The 49-year-old al-Libi was interrogated aboard a U.S. Navy warship for a week before being brought to New York on Saturday.
