Here's a key quote:

Donors in Saudi Arabia and the United Arab Emirates are estimated to have been sending up to $100 million annually to radical Islamic schools in Pakistan that back extremist groups, according to a leaked US diplomatic cable.

The cable alleged that financial aid for a "sophisticated jihadi recruitment network" was coming from "missionary" and "Islamic charitable" organisations in the Gulf, ostensibly with the direct support of the Saudi and UAE governments.
