Pakistan Says It Killed 13 Afghan Taliban Fighters in Gulistan Border Clash

Pakistan says its forces killed at least 13 Afghan Taliban personnel overnight on September 24-25, 2026, in a clash in the Gulistan sector of southwestern Balochistan — a claim Kabul flatly denies, saying instead that its forces destroyed a Pakistani border post in the same encounter.

What Pakistan says happened

Pakistan's Information Ministry said in a statement that its forces repelled what it called an "attempted Afghan aggression" in Gulistan, near the Chaman border crossing opposite Afghanistan's Spin Boldak district. The ministry said at least 13 Afghan Taliban personnel were killed and several more wounded, and released video footage it said showed Pakistani forces firing artillery toward Afghan positions during the overnight fighting.

Kabul's account is the opposite

Afghanistan's Ministry of Defence rejected Pakistan's version outright, denying that Afghan forces suffered any losses in the encounter. Instead, it said Afghan forces destroyed a Pakistani border post near Spin Boldak. Build Better Pakistan could not independently verify either side's casualty or damage claims, and no neutral confirmation of the incident had emerged as of this writing.

The fourth flashpoint in ten days

Gulistan is the latest and, on Pakistan's count, the bloodiest in a sequence of border incidents that has unfolded with unusual speed. Pakistani troops repelled an infiltration attempt into Kurram and exchanged fire with Afghan Taliban forces on September 22-23, then Pakistan struck 10 sites across Khost, Paktia and Kandahar before dawn on September 24, a response it said targeted drone-launch sites after accusing the Taliban of flying drones into Khyber Pakhtunkhwa. Kabul said those strikes killed four civilians and vowed an "appropriate response." The Gulistan clash, less than 24 hours later, is the clearest sign yet of what that response has looked like on the ground — a shift in geography from the eastern Afghan provinces struck on September 24 to Balochistan's southwestern frontier, opening a second active stretch of the border in the same week.

What's underneath the dispute

The underlying disagreement between the two governments has not moved: Pakistan says the Afghan Taliban administration shelters Tehreek-e-Taliban Pakistan fighters who stage attacks on Pakistani soil, including the September 18 car bombing of a Kohat police station that killed 16 officers and set off this month's escalation. Kabul denies harbouring the group and says Pakistani military action is what's actually killing people on Afghan territory. Each new incident hardens both positions rather than resolving them, and each side's numbers — Pakistan's Afghan Taliban body count, Afghanistan's Pakistani civilian body count — arrive without independent verification and are disputed by the other side within hours.

The mediators' problem gets harder

Regional diplomats from China, Turkey, Qatar and Saudi Arabia have spent much of 2026 trying to broker a durable de-escalation framework between Islamabad and Kabul. A clash in Balochistan, on top of strikes reaching Kandahar in the south and repeated incidents in Kurram and Khyber Pakhtunkhwa in the east, means any renewed talks would now need to address fighting spread across nearly the entire length of the Pakistan-Afghanistan frontier rather than a single contained sector — a considerably harder problem to put back in a box.

Why this reaches beyond the border

A security establishment already running sustained counter-militancy operations in Balochistan against the BLA is now managing an active Afghan Taliban front in the same province, on top of the eastern flashpoints in Kurram and Khyber Pakhtunkhwa. That's a wider commitment of security resources than Pakistan has had to sustain on this frontier at any other point in 2026, and it comes as Afghan trade routes through Chaman and Torkham have already faced repeated disruption this year — a cost that lands on ordinary trade and transit long before any ceasefire is negotiated.

What to watch next

Whether Chaman crossing stays open, whether either government allows independent verification of casualty figures, and whether the China-Turkey-Qatar-Saudi mediation track can still function across a frontier now active in both its eastern and southwestern sectors are the questions that will determine whether this week marks a peak in the escalation or just its latest step.
