Pakistan returned 252 Afghan nationals to their home country as a gesture of goodwill, as the Pak-Afghan border remained closed on the ninth day, after a wave of terrorism hit the country.

The Afghan nationals who were returned on Friday spent a week on the footpath as the Torkham border remained closed. Among them were women and children.

Trade and movement at the border has been suspended while security is on high alert. However, people with valid travel documents have been allowed to cross the border on foot.

The Pakistan-Afghanistan border was closed on February 18 due to security reasons,the Inter-services Public Relations, hours after a bomb ripped through a shrine in interior Sindh leaving at least 80 people dead.

At least 80 people were martyred Thursday when a suicide bomber attacked the crowded Sufi shrine of Lal Shahbaz Qalandar in Sehwan, injuring up to 250 others.

Pakistan Army pounded militant hideouts inside Afghanistan last week and killed militants belonging to Jamaat ul Ahrar.
