Heavy fighting erupted along the Pakistan–Afghanistan frontier on the night of February 26, and Islamabad announced a dramatic escalation the following day. Pakistan's defence minister, identified in Pakistani media as Asif, wrote on X that "our patience has run out" and declared that Pakistan and the Afghan government were now in an "open war."
Afghan government spokespeople confirmed overnight strikes on parts of Kabul, Kandahar and Paktia provinces, saying that Pakistani aircraft had bombed areas of the capital and southern provinces; no casualties have been reported so far. Pakistani military sources told state-aligned outlets that the pre-dawn operations destroyed Afghan command posts, ammunition depots and logistics bases and were retaliation for an attack on Pakistani border posts on February 26.
The latest exchanges form part of a months-long pattern of intermittent cross-border firing in eastern Afghanistan, including in the border provinces of Khost, Kunar and Nangarhar. Islamabad and Kabul have repeatedly failed to stabilise the frontier since a truce agreement brokered last October under the auspices of Qatar and Turkey; subsequent rounds of talks in Doha, Istanbul and Riyadh did not produce a durable settlement.
The public rhetoric and strikes mark a sea change. Air operations reaching Kabul, the Afghan capital, represent a rare and serious escalation of state-on-state confrontation, breaching norms of sovereignty and heightening the risk of wider confrontation. Pakistan frames the action as a security imperative against militants who it says use Afghan soil to strike Pakistani forces and border posts, but striking another country's major cities invites international scrutiny and potential diplomatic fallout.
The confrontation has immediate humanitarian and geopolitical implications. Renewed hostilities could trigger fresh refugee flows across an already porous frontier, disrupt trade and cross-border livelihoods, and complicate international efforts to engage the Taliban-led administration in Kabul. Neighbouring states and mediators such as Qatar and Turkey face pressure to prevent further escalation while Islamabad and Kabul appear set on reciprocal military responses.
For Pakistan, the decision to go public with a declaration of war may also be shaped by domestic politics and military signalling. For Kabul, the strikes test the Taliban-led government's capacity to control territory and prevent militant groups from operating across its borders. The coming days will be decisive: a rapid diplomatic de‑escalation would be necessary to prevent a wider regional crisis, but the public tone from both capitals suggests the path back to quiet may be fraught.
