The sources said Afghan nationals were involved in attacks in Peshawar, Bannu, Besham, North Waziristan, Tank and Dera Ismail Khan.
The five-page dossier obtained by Afghanistan International contains names, aliases, dates of attacks and photographs of the individuals.
Pakistani officials have repeatedly claimed in recent years that Afghan nationals were involved in attacks inside the country.
The security sources said the documents support Islamabad’s longstanding position that Afghan nationals and Afghan territory have been used to organise and plan suicide bombings and other militant attacks in Pakistan.
Pakistani security officials said the information forms part of an effort to document the alleged involvement of Afghan nationals in attacks across the country.
Most recently, Pakistan’s military said the attacker behind the assault on a Rangers camp in Karachi was an Afghan national who was arrested after being wounded.
Responding to Pakistan’s claims, Taliban spokesperson Zabihullah Mujahid described the allegations as illogical. He said Pakistani officials blamed the Taliban whenever an explosion occurred in Karachi or elsewhere in the country.
He added that Pakistan should focus on securing its own cities instead of accusing others.
The Taliban administration has consistently denied allegations that Afghan nationals are involved in bomb attacks in Pakistan.
Since late 2025, repeated clashes have taken place between Pakistani forces and the Afghan Taliban, leading to heightened security tensions along the border.
Over the past five years, Pakistan has carried out at least 13 air and artillery strikes inside Afghanistan.
Islamabad says members of the Tehreek-e-Taliban Pakistan are based in these areas and use Afghan territory to plan and launch attacks against Pakistan, a claim the Taliban deny.
