WikiLeaks was already established as an online outlet for posting secret documents from anonymous leakers well before its massive disclosure of U.S. government and military information in 2010. That was the year WikiLeaks' Australian founder, Julian Assange, faced allegations that led to his seeking asylum in Ecuador's London embassy.

Here is a timeline of WikiLeaks' key disclosures and related developments.

The U.S. State Department is offering a reward of $1 million for information leading to the location of Hamza bin Laden, the son of 9/11 mastermind Osama bin Laden.

The State Department on Thursday announced that Hamza bin Laden has been added to its Specially Designated Global Terrorist list.

The action also imposes sanctions on the son of Osama bin Laden.

Hamza bin Laden was added to the terror list after he was "determined to have committed, or pose a serious risk of committing, acts of terrorism that threaten the security of U.S. nationals or the national security."

For many of us, Sept. 11, 2001, is one of those touchstone dates — we remember exactly where we were when we heard that the planes hit the World Trade Center and the Pentagon. I was in Afghanistan.

I'd arrived in Kabul on Sept. 9 to cover the trial of eight foreign aid workers who had been arrested by the Taliban regime, which accused them of preaching Christianity to Afghans. Proselytizing was a death penalty crime, and two Americans were among the accused.

A handwritten will by Osama bin Laden said he had a fortune of "about 29 million dollars" and that most of it should be spent "on Jihad," according to documents released by the U.S. government on Tuesday.
