On Saturday, Pakistan partially opened the Torkham border crossing with Afghanistan to allow thousands of Afghan refugees to return home.
All other forms of cross-border movement, including trade, remain restricted.
Pakistan closed all border crossings with Afghanistan following deadly clashes on October 12, which both sides said killed dozens of soldiers.
The opening came after Pakistan and Afghanistan agreed to a ceasefire following nearly a week of talks brokered by Turkey and Qatar, aimed at preventing a wider conflict in the region.
