The main land border crossing between Pakistan and India is a pivotal conduit for trade and passenger movement, and is also significant for Afghanistan.
Its closure and disruption to the movement of goods and people is expected to have the most immediate effect on small traders and industries reliant on cross-border trade, as well as Pakistanis trying to leave in the aftermath of the attack.
The Attari-Wagah crossing saw trade worth 38.86bn Indian rupees ($454m) in the 2023-24 fiscal year, with 6,871 cargo movements and 71,563 passenger crossings recorded, according to The Times of India.
Afghanistan also trades goods with India, passing through Pakistan and this crossing, something that will now be disrupted.
