Major Nidal Malik Hasan attended same Virginia mosque as several 9/11 hijackers

Major Nidal Malik Hasan worshipped at a mosque led by a radical imam said to be a "spiritual adviser" to three of the hijackers who attacked America on Sept 11, 2001.

Hasan, the sole suspect in the massacre of 13 fellow US soldiers in Texas, attended the controversial Dar al-Hijrah mosque in Great Falls, Virginia, in 2001 at the same time as two of the September 11 terrorists, The Sunday Telegraph has learnt. His mother's funeral was held there in May that year.

The preacher at the time was Anwar al-Awlaki, an American-born Yemeni scholar who was banned from addressing a meeting in London by video link in August because he is accused of supporting attacks on British troops and backing terrorist organisations.

As investigators look at Hasan's motives and mindset, his attendance at the mosque could be an important piece of the jigsaw. Al-Awlaki moved to Dar al-Hijrah as imam in January, 2001, from the west coast, and three months later the September 11 hijackers Nawaf al-Hamzi and Hani Hanjour began attending his services. A third hijacker attended his services in California.
