Hasan Mahsum (or Hassan Makhdum), also known as Abu-Muhammad al-Turkestani and Ashan Sumut, was the leader of the Islamic extremist group East Turkestan Islamic Party, and suspected of having ties with Al Qaeda. He was shot dead in a counter-terrorism operation on October 2, 2003 by the Pakistani Army.

In 1989 Zeydin Yusup started the group which was originally called East Turkistan Islamic Party(ETIP). The movement was reshuffled by Hasan Mahsum and Abudukadir Yapuquan in 1997 into its present incarnation.
Mahsum, a native of Shule (Kunixar) County, became involved with the East Turkestan independence movement early in his life; in his late 20s, he was already a lecturer at a training camp in Yecheng County, preaching Jihad and advocating the use of violence against Chinese authorities. He was arrested in October 1993 by the Chinese police for terrorist activities and sentenced to three years of re-education through labour. After fleeing China in 1997 to Mecca, Mahsum joined the Taliban and lived in Afghanistan and Pakistan; he held an Afghan passport issued by the Taliban. In early 1999, he was said to have met with Osama bin Laden, who offered him US$300,000 of financial assistance for the East Turkestan Islamic Movement in the following year; Mahsum himself denied any connection with bin Laden. The Chinese government has accused him of directing a series of violent terrorist activities including robbery and murder in Urumqi on February 4, 1999 and violent murders in the Khotan region on December 14, 1999; it is believed that these attacks were carried out by an operative of his named Mutalif Kasim.

Testimony of Uyghur inmates at Guantanamo Bay on Hasan Mahsum
Several of the Uyghur captives in Guantanamo acknowledged having met or having seen, an individual named Hassan Mahsum at a camp in eastern Afghanistan in mid to late 2001.
The purpose of the camp outside of Jalalabad, Afghanistan, where the Uighurs lived for months prior to the United States invasion of Afghanistan, is disputed. Many of the Uyghur captives in Guantanamo claimed that the camp was simply a place for Uyghurs fleeing "Chinese oppression" gathered. Seema Saifee, a lawyer for four of the Uyghurs called the camp an "expatriate village in the mountains." The United States Intelligence Community considers the camp to be a terrorist training facility hosted by the Taliban and funded by Al Qaida. The camp was located in Nangarhar Province, a majority Pashtun area known for its support of the Taliban, and was surrounded by Al Qaida training camps such as the Derunta Camp.
Uyghur captive Abdullah Abdulqadirakhum identified Hasan Mahsum as the man who provided him with training on the AK-47.
American intelligence analysts identified the camp the Uyghurs were constructing as a militant training camp, and alleged that the Taliban and al Qaeda were sponsoring the Uyghur's military training there. Abdulqadirakhum, and the other Uyghurs, all said the training they were provided was minimal, lasting a few hours, at most, and that most of their time and energy was consumed in their construction work.
Some of the Uyghurs denied receiving any training. They said it was optional, and they had opted out. All the Uyghurs, except Abdulqadirakhum, who acknowledged receiving some training, identified a fellow Uyghur named Abdul Haq as their trainer.
Abdulqadirakhum said that Maksum was killed during the US bombing campaign.
Uyghur captive Bahtiyar Mahnut testified that he saw Mahsum visit the camp once. Bahtiyar Mahnut acknowledged that Hassam Mashum was a Uyghur leader. He disputed, however, that he was a leader of the Eastern Turkistan Islamic Movement Template:Sic, the Eastern Turkestan Organization Template:Sic or the Eastern Turkistan Islamic Party. He testified that during their long resistance to Chinese occupation the Uyghur people had formed a number of groups with names similar to those mentioned in the allegations, but, to the best of his knowledge, Hassan Mashum was a leader of the Freedom Movement Party or the Freedom Organization
Bahtiyar Mahnut did not find the allegation that Hassan Mashum would be allied to al Qaeda credible.
