Osama bin Laden's journal found by U.S. sources who raided his northern Pakistan mansion last week reveals the deceased al-Qaeda leader urged followers make a single attack that would kill thousands of Americans, look beyond New York to other U.S. cities, and strike on significant days, according to a report.

No specific attacks were planned, U.S. officials told the Associated Press in a report on Thursday, revealing some of the contents of the journal on condition of anonymity because they were not authorized to speak publicly.

Last week, the FBI warned bin Laden was considering targeting trains, citing intelligence gathered from the compound. No specific plot was announced.

The journal contents cited on Thursday show bin Laden communicated with people in al-Qaeda affiliated groups, as well as the organization's Yemen branch.

He told followers not to limit attacks to New York, according to report. He said other targets such as Los Angeles or smaller cities should be considered.

U.S. officials said the information obtained by Navy SEALs from computers and storage devices on the compound reveals that counterterrorism officials underestimated Bin Laden's role in running Al-Qaeda.

The documents should dispel the notion that Bin Laden had become just an inspirational figure head, they said.

U.S. officials on Saturday released five videos from Bin Laden's collection at the compound that had sound edited out. They said they did not want to act as a propaganda channel for bin Laden.

Administration officials said the videos were part of the greatest intelligence haul from a senior terrorist they had ever gotten.

The FBI and Homeland Security Department collected computers and portable storage devices from bin Laden's compound.

Officials said Thursday it will take weeks, if not months to go through all the findings, according to the report.

President Barack Obama said in an interview last week that bin Laden had some sort of support network inside Pakistan that allowed him to go unnoticed over the past several years he was living at the compound.

U.S. and Pakistan authorities are investigating who and what those networks actually were.

Pakistan currently has some of Osama's wives in custody who were left behind after the attacks. The U.S. planned to take some survivors of the compound raid with them but were reportedly not able to after one of the helicopters being used failed and was destroyed in an attempt to avoid the release of important U.S. military technology.
