Bullet-riddled bodies of six Pakistanis, who were kidnapped in Afghanistan about two months back and killed a few days ago, were handed over to Pakistani officials at Torkham border post on Wednesday.

Relatives of the deceased had said that gunmen kidnapped nine Pakistanis, belonging to the Charsadda district, in Mamand area of Afghanistan’s Nangarhar province about two months ago.

One of the kidnapped men, Lehaz Gul, was later freed, apparently because he was too old, they said. The whereabouts of two other missing men is still not known.
