Islamabad's Airstrikes Refresh a Cycle of Pakistan-Afghanistan Violence Analysts Say Has No End in Sight

A fresh round of Pakistani air strikes inside Afghanistan has revived a conflict that once seemed destined to fade, and the latest exchange has again left analysts asking how long the two governments can avoid sliding into all-out war. The escalation was the central subject of a recent Al Jazeera Inside Story discussion, published on 26 September 2026, which examined why the violence between the two neighbours keeps returning despite repeated efforts to stop it.

The episode opened with a simple but stark premise: Pakistan and Afghanistan, once close allies, have become enemies. That reversal is relatively recent. In 2021, when the Taliban seized power in Kabul, Pakistan's government in Islamabad publicly celebrated the move, treating the Taliban's return as a victory of the kind that had been sought for years. The sense that a long-running source of instability had finally been resolved, and that a friendly government had taken charge in Kabul, briefly defined the relationship between the two countries.

That optimism did not last. Relations deteriorated steadily after 2021, and the collapse of the alliance has been as much about suspicion as ideology. Pakistan has repeatedly accused the Afghan government of providing shelter, sanctuary and support to the Pakistani Taliban, known as the TTP, as well as to other armed groups that have claimed responsibility for attacks carried out inside Pakistan. Those attacks have become a defining security problem for Islamabad, and the allegation of harbouring the attackers sits at the centre of the diplomatic rupture.

Kabul has flatly denied sheltering or backing those fighters. The competing claims have proved almost impossible to verify, and that gap between accusation and denial has become one of the central obstacles to any durable settlement. With neither side willing to accept the other's account, each continues to act on its own version of events — and each move by one government is read by the other as proof of bad faith.

The on-the-ground escalation recorded in recent days illustrates just how tight the cycle has become. On 21 September, Afghan authorities said three people were killed in Pakistani air attacks. Four days later, on 25 September, Pakistani forces reported killing Afghan Taliban fighters in a border confrontation described as an escalation. The pattern of tit-for-tat violence, in which a strike inside one country's territory is answered by a military response in or near the other, has continued into late September.

The latest such incident is a suicide bombing in Dera Ismail Khan, in Pakistan's Khyber Pakhtunkhwa province, which killed at least 12 people on 26 September. The attack, which was the same day the Inside Story episode was published, underscores the scale of the security crisis Pakistan says it is trying to address — and the geographic concentration of the violence in the north-west of the country, near the Afghan border.

That geography matters to the analysis. The conflict is not confined to a single disputed zone or a formal frontier line; it stretches across border areas where state authority is thin, armed groups operate with relative ease, and local grievances overlap with national rivalries. Airstrikes, border firefights and suicide bombings feed into one another, each cycle making the next round more difficult to contain.

The Al Jazeera panel assembled to discuss the cycle brought together regional and diplomatic perspectives. Adrian Finighan presented the discussion, which featured Syed Akhtar Ali Shah, a former inspector general of police in Khyber Pakhtunkhwa, bringing experience of policing and security management in the province most affected by the violence. The programme also included Faiz Zaland, a professor of political science at Kabul University, offering an Afghan academic viewpoint, and Michael Semple, a former EU representative in Afghanistan, who has spent years working on the diplomatic and international dimensions of the country's politics.

The framing of the discussion reflects the sense, shared across the panel's areas of expertise, that the problem is structural rather than personal. Police experience highlights the limits of security responses at the provincial level; Afghan scholarship speaks to how the Taliban government has been perceived and governed; and diplomatic experience underscores how international actors have repeatedly sought to bridge the gap without managing to alter the underlying dynamics.

A central question raised by the episode is what the fallout of this cycle of violence will be. Every exchange of fire carries the risk not only of direct confrontation between two national militaries, but of a wider regional war, further displacement and a deepening sense of insecurity among civilians on both sides of the border. The presence of armed groups complicates matters further, since retaliation against a government is often indistinguishable from retaliation against the non-state fighters it is accused of sheltering.

Diplomacy, so far, has not delivered. Many attempts to stop the fighting have failed, and each collapsed initiative has left both governments with more reason to distrust the other. Without a working mechanism to verify claims, communicate and halt strikes, the pattern established in recent weeks — an air attack, a border clash, a bombing — is likely to continue, unless the underlying accusations about the TTP and other militant groups are addressed in a way both Kabul and Islamabad can accept.

For now, the region waits as another round of violence follows another, with the guests on the Inside Story discussion offering the clearest signal of where things stand: two former allies, each convinced the other is responsible for the killing, and neither willing to make the first concession.
