The Afghan government freed 65 suspected Pakistani militants on Monday, the latest group to be released after being caught fighting for the Taleban during the US-led war in late 2001.
According to the Pakistani government, around 500 more Pakistani nationals are in Afghan prisons.
Pakistani diplomats have welcomed the releases as a positive move towards improving relations between the two countries. One Pakistani diplomat in Kabul said he hoped the rest of the prisoners in Afghanistan would be released soon.
