Usama bin Laden reportedly has a new terrorist assigned to targeting the West.
Saif Al-Adel, a native of Egypt, is Al Qaeda's new chief of international operations, Britain's The Telegraph reported, citing unnamed U.S. and Pakistani sources.
But sources tell Fox News that investigators cannot agree on whether Al-Adel has taken on one of Al Qaeda's top operational positions, partly because there is disagreement over whether Al-Adel is still hiding in Iran.
The respected NEFA foundation, which tracks terrorists worldwide, cites a European intelligence source who says Al-Adel is believed to be in Waziristan, part of the tribal areas of Pakistan.
Al-Adel has served as the head of the military committee of Al Qaeda after the death of Mohammed Atef in late 2001, making him the commander over Khalid Sheikh Muhammad.
He also has a longstanding working relation with Iran, going back the early 1990s, when he went from Sudan to Lebanon to be trained by Hezbollah in improvised explosive devices, or IEDs.
Al-Adel was the coordinator of the May 2003 attacks in Saudi Arabia and probably Morocco. He was captured, but last March, he was released in exchange for an Iranian diplomat who was kidnapped in the tribal areas of Pakistan two years earlier.
