Just so LEJ and TTP both have their origins in Sipah e Sahaba
https://wikileaks.org/plusd/cables/09ISLAMABAD2576_a.html
The Sipah-e-Sahaba Pakistan (SSP) was formed in 1985
in Jhang, Punjab by anti-Shia clerics. This banned terrorist
organization is focused on sectarian violence and
the group
was originally supported by Zia-ul-Haq's government in a move
to counter Shia Iran's influence in Pakistan. The funding
for SSP comes from both external and local sources such as
the trader-merchant class in Jhang. SSP was responsible for
the rise in sectarian violence in the 1980s and 1990s. SSP
advocates Deobandi ideology and has served as the basic
ISLAMABAD 00002576 003 OF 004
ideological and militant birthing ground for other militant
groups. The group was linked with the 1997 attack on former
prime minister Nawaz Sharif, and they take credit for killing
several Shia doctors in Karachi in 2001. Recently, the SSP
has resurged in Southern Punjab and has links with other
militant outfits.
Qari Hussain, the most feared deputy of
Tehreek Taliban Pakistan's (TTP) recently killed leader,
Baitullah Mehsud, came out of SSP and many of the TTP's foot
soldiers are from SSP ranks. (Note. The SSP is also believed
to be behind the violence against Christians in Punjab in
late August and early September 2009. End Note.)
¶10. (C)
Lashkar-e-Jhangvi (LeJ) grew out of SSP and was
founded in Bhakkar, South Punjab.
The Deobandi organization
was initially focused on the elimination of Shias, but after
9/11 its attention shifted to fighting the war on terror
against the United States.
