Taliban’s name meaning ‘students’ itself shows that they are the students of madressahs. And we all know their terrorism against Muslims of Pakistan.
One example:

IN July, the ISI released a dossier describing the connection between madressahs and militant networks. To illustrate the issue, the dossier presented the case of Fidaullah Yousufzai, a 24-year-old who was educated at Islamabad’s Lal Masjid and four other seminaries before joining the militant Ghazi Force.
An interesting report on link between madressahs and terrorism:
