An October 23, 2007 commentary piece written by Benazir Bhutto stated:

I had received credible information that I was being targeted by elements that wanted to disrupt the democratic process--specifically that Baitul Masood (an Afghan who leads the Taliban forces in North Waziristan), Hamza bin Laden (an Arab), and a Red Mosque militant had been sent to kill me. ...

The Jerusalem Post reported:

Security officials in Pakistan's North West Frontier Province said Saturday they arrested a teenager allegedly involved in the assassination of former Prime Minister Benazir Bhutto last month.

The suspect, 15-year-old Aitezaz Shah, told investigators he had been part of a five-man squad deployed that day in the city of Rawalpindi, where Bhutto was killed, a senior intelligence official said on condition of anonymity because he was not authorized to speak to media...

The intelligence official said Shah had told investigators that the team of assassins had been dispatched by Baitullah Mehsud, a militant leader from the South Waziristan region, with strong ties to al-Qaida and an alliance with the Taliban in nearby Afghanistan...

Shah was arrested Thursday in Dera Ismail Khan with another militant identified as Sher Zaman, according to both officials.
