ISLAMABAD: Qari Saifullah Akhtar, a former suspected Al Qaeda militant and founder of the banned Harkat-ul-Jihad-Al Islami group, has been gunned down in Afghanistan.

According to reports, Akhtar was killed during a clash with Afghan security forces in Birmil area of Paktika province bordering Pakistan. Sources said his family has been informed that he has been killed.

Hailing from Chishtian, Qari Akhtar was an active leader of militants based in Afghanistan and Pakistan. He has previously worked as advisor of slain Taliban leader Mullah Omar, and was believed to have close ties to former Al Qaeda chief Osama bin Laden.

In 2008, Akhtar was arrested from Lahore in connection with the October 18 suicide bombing at Karachi's Karsaz area the previous year that narrowly missed former Prime Minister Benazir Bhutto but killed about 150 others.

In her book, which was published in February 2008, Bhutto had narrated in detail the suicide attacks targeting her welcome procession as well as the involvement of Qari Saifullah Akhtar in the assassination bid.

Among other high-profile attacks, Akhtar has also been linked to two assassination attempts against former President Gen (retd) Pervez Musharraf.

He was arrested and extradited from the United Arab Emirates on August 7, 2004 on charges of plotting the twin suicide attacks on General Musharraf in Rawalpindi in December 2003.

Earlier arrested for a failed coup plot in 1995, he was released after the dismissal of the second Bhutto government in 1996. Shortly afterwards, he was reported to have moved to Afghanistan where he was inducted into the cabinet of the Taliban ameer, Mullah Omar, as his adviser on political affairs.

Qari Saifullah was one of the few militant leaders from Pakistan who had escaped with Mullah Omar after the US-led Allied Forces invaded Afghanistan in October 2001.
