Christian Ganczarski, aka Abu Mohamed -- a German citizen born in Poland -- is at present lodged in a prison in France, where he spent last 15 years.
A sealed indictment in this regard was made public yesterday.
"Today, we publicly announce charges against Ganczarski alleging that he participated in the planning of plots to kill Americans with high-level al-Qaeda terrorists Khaled Shaikh Mohammad, Usama bin Laden and others," said US Attorney Geoffrey S Berman.
Ganczarski allegedly provided Al-Qaeda with expertise in logistics, computers, radio communications and the maintenance of weapons systems that would be used against Americans soldiers after the 9/11 attacks, said New York Police Commissioner James P ONeill.

Ganczarski worked for Al-Qaeda, lived in its camps and guest houses, he said.
He traveled from Germany to Pakistan and Afghanistan on at least five separate occasions between 1999 and 2001.
During these trips, he became associated with Al-Qaeda and developed personal relationships with bin Laden, Abu Hafs el Masri, al Adel and Mohammad.
He participated in Al-Qaedas efforts to kill Americans in a number of ways, such as providing al Adel and other Al- Qaeda members with technological guidance and hardware, including computers, radios and other communications equipment.
In January 2000, Ganczarski attended a speech delivered by bin Laden at al Qaedas headquarters in Kandahar. The speech was attended by at least 100 men, including, among others, many significant Al-Qaeda leaders and terrorists.
