'...Mulla Omar...appointed Mulla Obaidullah and Mulla Abdulghani Baradar as his deputies...both were direct founders of the Taliban....Obaidullah
belonged to the Alokozay and Baradar to the Popalzay... This was a reaction to...Hamid Karzai...

...who contested Taliban in
Kandahar and aimed to undercut the Karzai’s appeal to
Durrani Pashtuns... The decision paid off and prevented the full take-over of the South by Hamid Karzai, Gul Agha Sherzay (Barakzay), Jan Muhammad (Popalzay) and Sher Muhammad Akhundzada (Alizay).'

'After the fall of Taliban... Mulla Muhammad Omar was separated from his family. His family came ...to Quetta and from there to Karachi. The family was sent back... to Quetta in 2005. In 2008 Aka Mulla Nur Muhammad (Omar's step father and paternal uncle) died in Quetta.'

'Mulla Omar had four wives. His first wife..was from the Hotak tribe of Uruzgan, she is the mother of Mawlawi Muhammad Yaqub (born around 1989) and eight other sons. This shows that Mulla Omar only married after Soviet forces had started their withdrawal.'

...Mulla Muhammad Hassan Akhund Babari... expressed himself in an interview... even Mulla Omar had lost courage. He said: “As we informed him about restoring the resistance, his response was that it was silly to confront US forces...

...Do whatever you want to, I have nothing to do with it. I began my prayers and will pray for God to defeat USA by His own might.”

'...many people sent their children to religious schools that were functioning under Taliban...With the overthrow of the regime, all these religious schools were closed and those students, who reached at this time their graduation period, remained without access to education...

...These students provided to be a fertile recruiting ground... they were from the beginning pro-Taliban, familiar with the social psychology of Taliban and on the other hand, these students were extremely excited after the fall of Taliban’s regime...

...The attacks of US on Afghanistan were in their eyes an obvious aggression and these attacks evoked them to take revenge. A large number of these young people, who were prosecuted, intimidated and irritated by pro-American warlords escaped to Quetta, Peshawar and other areas..'

'...as peace talks started between Taliban
affiliated with Ahmadzai Wazirs and Pakistani
government began in 2002/2004, the region became
less secure for foreign fighters. Therefore, many Afg Taliban moved to the region of the Mehsud and
constructed centers in mountainous areas.'

'The Haqqani Network has set up stricter
conditions for suicide attacks...attention was paid to the physical/psychological wellbeing of every suicide attacker. In contrary to TTP, children were not chosen...Every suicide attacker must be 16 years old, with an appropriate beard.'

'First, Islamabad had never given Taliban the impression
that they may have a free hand in...Pakistan. Rather, although Pakistan has tolerated on the one hand their activities...Pakistan strictly monitored,
prevented any activity that was independent of the interests of Pakistan'

'...To make their movement effective, Taliban needed strong leadership. They were however, not allowed to have such leadership, rather the members of their leadership circle came under attack by Pakistani authorities from time to time, when they became too independent...

..During these attacks, dozens of their leaders...were arrested. Among the arrested leaders, the former minister for defense, Mulla Obaidullah Akhund, the former minister for justice, Mulla Nooruddin Turabi, the former friend of Mulla Muhammad Omar and his right hand and deputy..

..Mulla Abdul Ghani Baradar were included.
Some... were released on the condition that they
may not rejoin the Taliban’s movement and some other
died mysteriously. Mulla Obaidullah Akhund died in detention... According to sources in his family, he died after severe torture.'

Mulla Nooruddin Turabi and the secretary of Mulla Muhammad Omar, Abdul Ahad Jahangirwal, were released after seven and eight years’ imprisonment when their health conditions reached a critical stage.'
