Afghan forces have claimed the capture of several Pakistani military posts along the volatile Durand Line, escalating tensions between the two neighbors.
Fighting has entered its fifth consecutive day, marking the heaviest border clashes in years.
The Afghan Defence Ministry said its forces carried out retaliatory strikes after Pakistani air raids inside Afghanistan.
Officials reported seizing multiple Pakistani positions, including three in Spin Boldak (Kandahar) and two in Ali-Sher (Khost).
Hostilities have also spread to Khost and Jalalabad, with casualties reported on both sides.
Pakistan’s air force had recently conducted strikes on what it described as militant hideouts inside Afghan territory.
The clashes highlight the fragility of Afghanistan–Pakistan relations, with fears of further escalation.
Analysts warn that prolonged fighting could destabilize border regions and disrupt trade and humanitarian access.
