Narrative:

While being marshalled into the parking spot in ZZZ; both captain and first officer verbalized and visually confirmed that the equipment parked along the building was clear of their path. While moving slowly along perpendicular to the parking spot; the first officer commented that the marshaller; while giving 'all clear' signals continuously; hadn't looked back at the wing at all. First officer confirmed there was wing clearance. The captain turned into the parking spot with continuous 'keep moving' signals from at least 2 marshallers. If power was applied to complete the turn; it was minimal. The parking was completed with no unusual signals from the marshallers. While deplaning; ground personnel notified the crew that a van; parking along the building; had been blown over from jetblast and people inside were injured.
