Documents found in the house where Osama bin Laden was killed a year ago show a close working relationship between top al-Qaida leaders and Mullah Omar, the overall commander of the Taliban, including frequent discussions of joint operations against Nato forces in Afghanistan, the Afghan government and targets in Pakistan.
The communications show a three-way conversation between Bin Laden, his then deputy Ayman Zawahiri and Omar, who is believed to have been in Pakistan since fleeing Afghanistan after the collapse of his regime in 2001.
