The madrassa in Akora Khattak in Nowshera district of the province is known for having several top Afghan Taliban leaders among its alumni, including former Taliban chief Mullah Omar who received an honorary doctorate from the seminary.
Specially designated global terrorist Sirajuddin Haqqani, who carries a reward of $10 million US bounty on his head, is the acting interior minister while his uncle -- Khalil Haqqani -- has been named as acting minister for refugees.
He was the chief of the hardline political party Jamiat Ulema-i-Islam-Sami.
Darul Uloom Haqqania madrassa, one of Pakistan's largest and oldest seminaries and dubbed as a 'university of jihad' by its critics for helping sow violence across the region for decades, has educated more Taliban leaders than any school in the world and its alumni now hold key positions in Afghanistan, according to a media report.
Jalaluddin Haqqani was closely tied to Al Qaeda leaders and had played a key role in supporting the terror group in both Afghanistan and Pakistan.
