Newly released papers from Osama Bin¹ Laden²'s hideout reveal a frustrated³ al-Qaeda leader struggling to control an unruly network, the US military says.

美国军方称，奥萨马·本·拉登藏身之处的最新调查结果显示，一位沮丧的基地组织领导拼命控制着一个难以驾驭的网络。

The documents seized during the raid on the Abbottabad compound were posted online by the research wing of the US military academy, West Point.

The papers show he was unhappy with affiliates⁴' attacks on fellow Muslims, urging them to target the US instead.

Seventeen documents were released from a cache of more than 6,000.

The 175-page cache was posted online by the US Military Academy's Combating Terrorism Center - in the week marking a year since Bin Laden's death.

'Vile⁵ mistakes'

The papers date from September 2006 to April 2011 and include letters from other al-Qaeda leaders.

Some documents suggest that the group had a strained relationship with Iran.

Letters reveal al-Qaeda's exasperation⁶（恼怒，恶化） with the way Tehran handled the release of detainees, including members of Bin Laden's family, expressing annoyance⁷ that the Iranians "do not wish to appear to be negotiating with us or responding to our pressures".

Meanwhile, there is no explicit⁸ reference to any institutional support from Pakistan, where the al-Qaeda leader lived for nine years.

The papers make mention of "trusted Pakistani brothers", but one reference suggests Bin Laden was wary⁹ of Pakistani intelligence.

He gave instructions to family members travelling to Pakistan to make sure they were not followed - in case the local intelligence chief trailed them to his location.

In some papers, Bin Laden and his inner circle emphasised that attacks on the US would ultimately weaken other enemies.

"Even though we have the chance to attack the British, we should not waste our effort to do so but concentrate on defeating America, which will lead to defeating the others," one letter said.

The documents also shed light on Bin Laden's concerns that Muslims were being alienated¹⁰ by the ideology¹¹ of jihad（讨伐异教徒） .

In a letter from 2010, Bin Laden wrote of "starting a new phase to correct [the mistakes] we made".
