A main border crossing between Pakistan and Afghanistan was closed after demonstrations by Afghans against Islamabad's decision to introduce biometric identification system at the Chaman border point.
Demanding that the new system be immediately abolished, a large number of Afghans living in Vesh, a business centre across the border, stoned the newly-built Friendship Gate and smashed windowpanes of several departments of Pakistan on Thursday.
A complete strike was observed in Vesh against the Pakistan government's move.
Pakistan has introduced the new system to check illegal border crossing and to curb Taliban movement.
The border was later reopened in the afternoon to facilitate women and children after negotiations between officials of Pakistan and Afghanistan
In another development a tripartite meeting of the top military officials of Pakistan, Afghanistan and NATO forces appeared to have ironed out differences over allegations that Pakistan failed to crackdown on Taliban.
Head of the International Security Assistance Force (ISAF) Commander in Afghanistan, Gen David Richards said that with an enhanced deployment of Pakistani troops in the border region, cross-border activity of insurgents had come down.
"This step has helped considerably in bringing down the graph of insurgency in Afghanistan as compared to last winter," he said.
The "reduction in incidents since autumn has much to do with the activities on Pakistani side of the border. We are the beneficiaries on that side of border. All what has happened is not the result of an idle activity," he said.
