One of the FBI's most wanted terror suspects has a court appearance in New York today.
Abu Anas Al-Libi is the accused mastermind of the 1998 American Embassy bombings in Kenya and Tanzania.
225 people were killed.
U.S. commandos snatched Al-Libi from the streets of Tripoli last week.
He was taken to a US warship in the Mediterranean and questioned by counter-terrorism experts.
Prosecutors may present a potential "smoking gun" witness at Al-Libi's trial.
Officials say Ali Mohammad was an Al Gaeda double-agent who could testify about helping Al-Libi plan the embassy bombings in Kenya and Tanzania.
If convicted, Al Libi could get life in prison, or the federal death penalty.
It could be a year before the trial begins.
