Laufman said Abu-Ali, who once lived in Falls Church, joined an al-Qaida cell in Saudi Arabia in 2001, and was told he needed to either organize a terrorist operation or return to the United States and establish an al-Qaida cell.
Benkhala had Abu-Ali's phone number on a handwritten address list, Laufman said.
The phone list also included a contact for Ibrahim Buisir, a Libyan-born resident of Ireland who ran an Islamic charity suspected of funneling money to bin Laden, Laufman said.
