CNN.com - U.S. officials: Al Qaeda agent arrested in Iraq [make that two?]

who is Ghul, and what does he have to do with Husam al Yemeni?
A senior al Qaeda operative was captured Thursday in Iraq by friendly foreign forces and turned over to U.S. intelligence personnel, senior U.S. officials said.
A U.S. official told CNN that Ghul is a "longtime facilitator, operator" within al Qaeda, and a "significant player."
It is believed that Ghul was captured soon after his arrival in Iraq, the official said.
Earlier Friday, Pentagon sources announced that U.S. forces had captured a man described as a top lieutenant to a man connected to Ansar al-Islam, a Kurdish guerrilla group that U.S. officials say is linked to Osama bin Laden's terrorist network.
The suspect, identified as Husam al Yemeni, was captured last week along with other suspects during a raid near Fallujah in central Iraq, sources told CNN.
He is said to be a key associate of Abu Musab Al-Zarqawi. Pentagon officials call the capture "significant" and say it suggests they may be getting closer to finding Zarqawi.
In his address to the United Nations on February 5, 2003, Secretary of State Colin Powell named Al-Zarqawi's presence in northern Iraq as evidence of a "sinister nexus between Iraq and the al Qaeda terrorist network."
The commander of U.S. ground forces in Iraq had recently discussed his suspicion that insurgents in Iraq, whose tactics resemble those of al Qaeda, may be receiving financial support from the terror group, in the country said.
"I think it's probably not appropriate for me to talk about al Qaeda in the sense of a concrete, proven presence," Lt. Gen. Ricardo Sanchez said. "We're seeing al Qaeda-like tactics. We believe that there's training that's been conducted for some of the terrorists."
