Afghanistan-Pakistan Conflict

Afghanistan-Pakistan Conflict, series of skirmishes between Afghanistan and Pakistan that began in October 2025 amid growing tensions between Afghanistan’s Taliban-led government and Pakistan’s military establishment. Although Pakistan initially sought international backing for the Afghan Taliban when it took control of Afghanistan in 2021, attacks in Pakistan by Tehreek-e Taliban Pakistan (TTP; sometimes called Pakistani Taliban) surged after the takeover. Pakistani officials have since accused the Afghan Taliban of aiding the TTP, a group that shares the Taliban name but has separate leadership and objectives from the Afghan organization. Pakistani officials claimed to target the TTP in its initial air strike on Kabul, the capital of Afghanistan, in October 2025 but soon began placing blame on the Afghan Taliban as Afghan forces became involved in the fighting.

The skirmishes

The first significant confrontation took place on October 9, 2025. Following an attack a day earlier in Khyber Pakhtunkhwa province by the TTP on Pakistani soldiers, Pakistan carried out an air strike in Kabul that targeted Noor Wali Mehsud, the leader of the TTP. Mehsud survived the attack. Days later Afghan forces carried out retaliatory operations that killed at least 23 Pakistani soldiers and left at least 9 Afghan soldiers dead, although both sides claimed to have inflicted higher casualties. Ground fighting continued sporadically in the days ahead, and the skirmishes threatened to escalate into a broader conflict. International mediation led to a tenuous ceasefire later that month, but attempts to get the Taliban to crack down on the TTP were unsuccessful, and low-level confrontations continued to occur. On February 26, 2026, following weeks of rising tensions, Afghan forces launched a cross-border offensive on Pakistan, prompting Pakistan to conduct coordinated air and ground strikes the next day on military installations in Kabul, Kandahār, and areas along the border. As fighting continued, Afghan officials reported on March 16 that Pakistan had struck a hospital for drug rehabilitation in Kabul, killing more than 400 people and wounding more than 260 others. Pakistani officials claimed that they had targeted military installations and accused Afghanistan of exaggerating the casualties. Two days later they agreed to a temporary pause in fighting, brokered by Qatar, Saudi Arabia, and Turkey (Türkiye), in observance of Eid al-Fitr. Fighting escalated again in June after an attack, claimed by a militant group that had splintered from the TTP in 2014, on a security facility in Karachi and again in September after a suicide bombing, claimed by the TTP, inside a police compound in Khyber Pakhtunkhwa.

Background on Afghanistan-Pakistan border violence

The conflict took place amid increasing violence by nonstate actors along the two countries’ 1,600-mile- (2,600-kilometer-) border, a colonial-era demarcation (see Durand Line) whose settlement and geographic patterns make the area both contentious and difficult to control. Among the primary belligerents of the ongoing violence is the TTP, a discrete group from the Afghan Taliban that seeks to challenge the authority of the Pakistani government, particularly in the porous border region along Khyber Pakhtunkhwa province inhabited by Pashtuns. Although the Pakistani Taliban and the Afghan Taliban have occasionally encountered friction because the former opposes Pakistan and the latter seeks cooperation with Pakistan, the two groups possess common ground—reflected in their shared name—in ideology and culture as well as ethnic composition, and they have sometimes provided one another safe haven. Since the takeover of Afghanistan by the Afghan Taliban in 2021, the TTP has stepped up attacks in Pakistan. The Afghan Taliban, however, denies that the TTP is tolerated in Afghanistan.

Pakistan’s security backing

The air strike on Kabul also came at a time when Pakistan has been emboldened militarily, with strengthened defensive backing from its allies. Since mediating a brief conflict between Pakistan and India earlier in 2025, the United States has bolstered its ties with Pakistan and its chief of army staff, Asim Munir. Just weeks before the October 2025 air strike on Kabul, the United States indicated renewed interest in Afghanistan (after withdrawing in 2021) when U.S. Pres. Donald Trump called for the United States military to regain control of Bagram Air Base. Meanwhile, Pakistan entered into a mutual defense pact with Saudi Arabia in September, which stipulated that “any aggression against either country shall be considered an aggression against both.” The pact gave Pakistan greater security to pursue its military objectives while reducing the risk of a punitive response.
