* 1957 -- Osama bin Muhammad bin Awad bin Laden is born in Riyadh, Saudi Arabia. He is the 17th of 52 children fathered by Muhammad Awad bin Laden, a Yemeni immigrant who built a billion-dollar construction company in Saudi Arabia. His mother is Hamida al-Attas, who was from Syria.

* 1979 -- Bin Laden graduates from King Abdul Aziz University in Jeddah with a degree in engineering. He goes to Afghanistan to join the "jihad," or "holy war," against the Soviet Union. He remains there for a decade, using construction equipment from his family's business to help the Muslim guerrilla forces build shelters, tunnels and roads through the rugged Afghan mountains, and at times taking part in battle.

* October 1993 -- Eighteen U.S. servicemen, all of them part of a humanitarian mission to Somalia, are killed in an ambush in Mogadishu. Bin Laden later says that some Arab Afghans were involved in the killings and calls Americans "paper tigers" because they withdrew from Somalia shortly after the soldiers' deaths.

In the following months, officials believe he funds and directs a series of attacks, including a failed attempt to kill Egyptian president Hosni Mubarak and a 1995 suicide bombing at the Egyptian embassy in Pakistan. Authorities now believe that this marked the early days of a growing alliance between bin Laden and other militant Islamic groups, including the Egyptian Islamic Jihad and its leader Ayman al- Zawahiri.

"It wants to occupy our countries, steal our resources, impose on us agents to rule us."

Bin Laden also says that "Arab holy warriors" trained in Afghanistan had banded with Somali Muslims in October 1993 to kill 18 U.S. soldiers in a bloody battle on the streets of Mogadishu, Somalia. He says, "The U.S. today has set a double standard, calling whoever goes against its injustice, a terrorist. It wants to occupy our countries, steal our resources, impose agents on us to rule us, and then wants us to agree to all this. If we refuse to do so, it says we are terrorists."
