One member of the Taliban who was a witness told Reuters multiple people were injured, and the building and streets around the area were locked down by Taliban security forces.

Large crowds of Afghans have been thronging outside the passport office in a bid to get travel documents in recent days after the service was restarted after weeks of suspension.

Officials said that Thursdays are reserved as a special day for Taliban officials to visit the passport office to make travel documents.
