* Abdul Rahman Yasin was the only member of the al Qaeda cell that detonated the 1993 World Trade Center bomb to remain at large in the Clinton years. He fled to Iraq. U.S. forces recently discovered a cache of documents in Tikrit, Saddam's hometown, that show that Iraq gave Mr. Yasin both a house and monthly salary.

* Bin Laden met at least eight times with officers of Iraq's Special Security Organization, a secret police agency run by Saddam's son Qusay, and met with officials from Saddam's mukhabarat, its external intelligence service, according to intelligence made public by Secretary of State Colin Powell, who was speaking before the United Nations Security Council on February 6, 2003.

* Sudanese intelligence officials told me that their agents had observed meetings between Iraqi intelligence agents and bin Laden starting in 1994, when bin Laden lived in Khartoum.

* Bin Laden met the director of the Iraqi mukhabarat in 1996 in Khartoum, according to Mr. Powell.

* An al Qaeda operative now held by the U.S. confessed that in the mid-1990s, bin Laden had forged an agreement with Saddam's men to cease all terrorist activities against the Iraqi dictator, Mr. Powell told the United Nations.

* In 1999 the Guardian, a British newspaper, reported that Farouk Hijazi, a senior officer in Iraq's mukhabarat, had journeyed deep into the icy mountains near Kandahar, Afghanistan, in December 1998 to meet with al Qaeda men. Mr. Hijazi is "thought to have offered bin Laden asylum in Iraq," the Guardian reported.

* In October 2000, another Iraqi intelligence operative, Salah Suleiman, was arrested near the Afghan border by Pakistani authorities, according to Jane's Foreign Report, a respected international newsletter. Jane's reported that Suleiman was shuttling between Iraqi intelligence and Ayman al Zawahiri, now al Qaeda's No. 2 man.

* As recently as 2001, Iraq's embassy in Pakistan was used as a "liaison" between the Iraqi dictator and al Qaeda, Mr. Powell told the United Nations.

* Spanish investigators have uncovered documents seized from Yusuf Galan -- who is charged by a Spanish court with being "directly involved with the preparation and planning" of the Sept. 11 attacks -- that show the terrorist was invited to a party at the Iraqi embassy in Madrid. The invitation used his "al Qaeda nom de guerre," London's Independent reports.

* An Iraqi defector to Turkey, known by his cover name as "Abu Mohammed," told Gwynne Roberts of the Sunday Times of London that he saw bin Laden's fighters in camps in Iraq in 1997. At the time, Mohammed was a colonel in Saddam's Fedayeen. He described an encounter at Salman Pak, the training facility southeast of Baghdad. At that vast compound run by Iraqi intelligence, Muslim militants trained to hijack planes with knives -- on a full-size Boeing 707. Col. Mohammed recalls his first visit to Salman Pak this way: "We were met by Colonel Jamil Kamil, the camp manager, and Major Ali Hawas. I noticed that a lot of people were queuing for food. (The major) said to me: 'You'll have nothing to do with these people. They are Osama bin Laden's group and the PKK and Mojahedin-e Khalq.'"

* In 1998, Abbas al-Janabi, a longtime aide to Saddam's son Uday, defected to the West. At the time, he repeatedly told reporters that there was a direct connection between Iraq and al Qaeda.

*The Sunday Times found a Saddam loyalist in a Kurdish prison who claims to have been Dr. Zawahiri's bodyguard during his 1992 visit with Saddam in Baghdad. Dr. Zawahiri was a close associate of bin Laden at the time and was present at the founding of al Qaeda in 1989.

* Following the defeat of the Taliban, almost two dozen bin Laden associates "converged on Baghdad and established a base of operations there," Mr. Powell told the United Nations in February 2003. From their Baghdad base, the secretary said, they supervised the movement of men, materiel and money for al Qaeda's global network.

* In 2001, an al Qaeda member "bragged that the situation in Iraq was 'good,'" according to intelligence made public by Mr. Powell.

* That same year, Saudi Arabian border guards arrested two al Qaeda members entering the kingdom from Iraq.

* Abu Musaab al-Zarqawi oversaw an al Qaeda training camp in Afghanistan, Mr. Powell told the United Nations. His specialty was poisons. Wounded in fighting with U.S. forces, he sought medical treatment in Baghdad in May 2002. When Zarqawi recovered, he restarted a training camp in northern Iraq. Zarqawi's Iraq cell was later tied to the October 2002 murder of Lawrence Foley, an official of the U.S. Agency for International Development, in Amman, Jordan. The captured assassin confessed that he received orders and funds from Zarqawi's cell in Iraq, Mr. Powell said. His accomplice escaped to Iraq.

*Zarqawi met with military chief of al Qaeda, Mohammed Ibrahim Makwai (aka Saif al-Adel) in Iran in February 2003, according to intelligence sources cited by the Washington Post.

* Mohammad Atef, the head of al Qaeda's military wing until the U.S. killed him in Afghanistan in November 2001, told a senior al Qaeda member now in U.S. custody that the terror network needed labs outside of Afghanistan to manufacture chemical weapons, Mr. Powell said. "Where did they go, where did they look?" said the secretary. "They went to Iraq."

* Documents found among the debris of the Iraqi Intelligence Center show that Baghdad funded the Allied Democratic Forces, a Ugandan terror group led by an Islamist cleric linked to bin Laden. According to a London's Daily Telegraph, the organization offered to recruit "youth to train for the jihad" at a "headquarters for international holy warrior network" to be established in Baghdad.

* Mullah Melan Krekar, ran a terror group (the Ansar al-Islam) linked to both bin Laden and Saddam Hussein. Mr. Krekar admitted to a Kurdish newspaper that he met bin Laden in Afghanistan and other senior al Qaeda officials. His acknowledged meetings with bin Laden go back to 1988. When he organized Ansar al Islam in 2001 to conduct suicide attacks on Americans, "three bin Laden operatives showed up with a gift of $300,000 'to undertake jihad,'" Newsday reported. Mr. Krekar is now in custody in the Netherlands. His group operated in portion of northern Iraq loyal to Saddam Hussein -- and attacked independent Kurdish groups hostile to Saddam. A spokesman for the Patriotic Union of Kurdistan told a United Press International correspondent that Mr. Krekar's group was funded by "Saddam Hussein's regime in Baghdad."

* After October 2001, hundreds of al Qaeda fighters are believed to have holed up in the Ansar al-Islam's strongholds inside northern Iraq.
