Osama bin Laden was planning attack on U.S President

Osama bin Laden was planning to kill U.S. President Barack Obama and General David Petraeus, Commander of U.S. forces in Afghanistan, according to a report by CNN.

"Documents recovered from Osama bin Laden's compound in Pakistan show that al-Qaeda spoke of attacking President Barack Obama and Gen David Petraeus," CNN said quoting sources familiar with the materials recovered from the compound.

The documents refer to an attack that would destroy the aircraft carrying Obama and Petraeus in the Af-Pak region, it says.

The documents were bin Laden  "in his brainstorming mode", a U.S. official is quoted by CNN as saying.

Osama bin Laden was also working on a plan to attack the U.S. on the 10th anniversary of 9/11, according to material gathered by the Navy at his Pakistani compound.

He was working to assemble a team of militants, according to intelligence that Navy SEALs seized from his Pakistani hideout when they killed him this spring, the Wall Street Journal reports.

Bin Laden and his operations chief, Attiyah Abd al-Rahman, swapped views about the composition of the attack team, with bin Laden repeatedly rejecting names that Mr. Rahman suggested, according to U.S. officials familiar with the intelligence taken from the bin Laden compound, WSJ reports.

There were no signs the plot ever got beyond planning stage but the attack was possibly to be on trains on the anniversary of September 11.

US officials revealed in the days after the May 2 raid that killed Bin Laden that notebooks and computer files seized in the Navy SEAL operation showed he was wanting to stage more attacks against the U.S. and other Western targets, The International Herald Tribune reports.

Bin Laden wanted to strike at major U.S. cities, including Los Angeles, and to hit trains as well as airplanes, and mentioned key dates such as America’s July 4 Independence Day celebrations and the upcoming 10th anniversary of the September 11 attacks, they said.

Bin Laden may have been losing his grip on control of the terror group, the U.K's Daily Mail reports.

According to other materials in the treasure trove of documents found at his Abottabad lair, he was often ignored by his henchmen, it reports.

'What we found was that he was very isolated, and it is clearly the case he was struggling to continue to hold on to the type of influence and to direct operations in ways he may have been able to do in the past," a U.S. official said.

Counter-terrorism staff from half-a-dozen U.S. agencies have now raked over the entire bounty collected from the raid, but have had little success extracting any concrete leads from the documents.

The two phone numbers that Bin Laden had sewn into his clothing at the time of his death led nowhere, they added.
