Since February 2026, Pakistan and Afghanistan have been engaged in the most sustained cross-border conflict between the two countries since the Taliban's 2021 return to power in Afghanistan. The conflict began with Pakistani airstrikes on alleged Pakistani Taliban (TTP) and Islamic State – Khorasan Province camps in eastern Afghanistan, and escalated within a week into what Pakistan's defence minister, Khawaja Asif, called an "open war" fought under the codename Operation Ghazab lil-Haq.
The war has combined air and artillery exchanges along the Durand Line with a parallel insurgency inside Pakistan, as the TTP and allied groups intensified attacks in Khyber Pakhtunkhwa and Balochistan. Two ceasefire agreements for the Islamic holidays of Eid al-Fitr and Eid al-Adha briefly reduced hostilities but did not end them; fighting continued at lower intensity through the summer of 2026 and flared again in September following a mass-casualty attack in Kohat, Pakistan.
Background
The conflict occurred against the backdrop of long-running tensions between Afghanistan and Pakistan rooted in disputes dating back to the independence of Pakistan in 1947. Afghanistan has historically challenged the legitimacy of the Durand Line, which forms the international border between the two nations, contributing to decades of strained relations and periodic clashes.
Relations deteriorated further following the Taliban's return to power in 2021 in the aftermath of the US withdrawal from Afghanistan. Pakistan has repeatedly accused Afghanistan of providing safe haven to militant groups, particularly the Tehreek-e-Taliban Pakistan (TTP), which has carried out attacks in Pakistan in order to establish an Islamic emirate, similar to the model of government in Afghanistan. Taliban authorities have generally denied these allegations.
Tensions escalated in 2025 after a surge in cross-border violence and militant attacks. In October 2025, some of the deadliest clashes in years led to a Qatar-mediated ceasefire, but its implementation proved to be fragile, and follow-up talks in Doha and Istanbul failed to produce a lasting agreement. Low-level skirmishes continued along the border in the following months.
In early 2026, Pakistan experienced a series of major attacks, primarily in its frontier provinces of Balochistan and Khyber Pakhtunkhwa, alongside a major suicide bombing in the capital of Islamabad. Pakistani officials attributed several of these attacks to militant groups operating from Afghan territory and warned that military action could follow if the Taliban did not act against these groups.
On 11 February 2026, Pakistani Defence Minister Khawaja Asif warned that Pakistan may take action against militants in Afghanistan before the start of the Islamic month of Ramadan if the Taliban failed to deter militant activities from the territory under their control.
Following further attacks in February, Pakistani officials signalled that their restraint had been exhausted, setting the stage for the airstrikes that began the conflict.
Course of war
First week (21–27 February)
During the night of 21 February, local sources in Afghanistan reported airstrikes in parts of Nangarhar, Paktika, and Khost provinces. In Nangarhar, strikes were reported in the Bihsud and Khogyani districts, while in Paktika, strikes were reported in the Barmal and Urgun districts. Local sources reported that the airstrikes in Nangarhar's Bihsud district struck a civilian home, trapping 23 people beneath the rubble. Pakistan's Ministry of Information and Broadcasting (MolB) stated that the Pakistani military conducted "intelligence-based selective targeting" of seven terrorist camps and hideouts along the Afghanistan-Pakistan border region. The Taliban claimed that the targets included civilian homes and a religious seminary.
In a late-night press release, Pakistani officials confirmed that the Pakistan Air Force (PAF), under the command of Air Chief Marshal Zaheer Ahmad Babar, had carried out airstrikes in Afghanistan. Officials said the strikes were selective and intelligence-based, and targeted seven militant camps and hideouts linked to the Tehrik-i-Taliban Pakistan (TTP) and the Islamic State – Khorasan Province (ISIS–K) near the Afghanistan-Pakistan border. Pakistani officials added that the strikes were conducted as retaliation for recent terror attacks in Islamabad, Bajaur, and Bannu. A Pakistani newspaper, citing military sources, reported that seven TTP hideouts in Nangarhar, Paktika, and Khost provinces were destroyed and that more than 80 militants were killed; however, Taliban officials only reported airstrikes in the Nangarhar and Paktika provinces, adding that an airstrike in Bihsud District killed 18 civilians, including 11 children. Taliban officials condemned the airstrikes and warned of a calculated response at an appropriate time.
Shayesteh Jan Ahadi, former head of the Paktia Provincial Council, stated that Pakistani airstrikes in several districts were very widespread and powerful. The United Nations Assistance Mission in Afghanistan (UNAMA) reported that Pakistan carried out airstrikes between 11:45 p.m. on 21 February and 12:15 a.m. on 22 February. UNAMA also reported that airstrikes in Paktika province damaged or destroyed infrastructure. On 23 February, UNAMA confirmed that over 13 civilians had been killed by the Pakistani airstrikes, with an additional seven injured.
Pakistan described the operation as a retributive response to a series of suicide bombings inside Pakistan, including the 6 February bombing of a Shia mosque in Islamabad that killed 31 worshippers (claimed by ISIS–K), and attacks in Bajaur and Bannu districts in Khyber Pakhtunkhwa during the early days of Ramadan. Pakistan also claimed that the strikes were "intelligence-based, selective operations" against seven camps and hideouts belonging to the Tehreek-e-Taliban Pakistan (TTP), its affiliates, and the Islamic State – Khorasan Province (ISKP). This was the seventh time Pakistan has carried out airstrikes in Afghanistan since the Afghan Taliban took over in August 2021.
The Taliban-led Afghan government condemned the strikes as a "blatant violation of Afghanistan's territorial integrity" and a breach of international law, stating that they hit civilian homes, a religious seminary, and other civilian structures, killing at least 18 people (including women and children) and leaving others missing under rubble. In addition, one family in Girdi Kas lost 18 of 23 members, and additional casualties were reported in Paktika. Afghan officials vowed an "appropriate and measured response" at a suitable time.
On 24 February, the hostilities resumed as both countries exchanged fire along their borders while both sides blamed each other for provocations. Zabihullah Noorani, head of the Afghan information department in eastern Nangarhar, stated that Pakistani troops carried out the first shots in the Shahkot area near the border. Pakistan claimed that its forces retaliated in response to a mortar and rocket from Afghanistan on Jarobi Kandao area of the Zakhakhel tehsil, with skirmishes later spreading to Wragha, Maro Sar, Shahkot and Zakhakhel. Pakistan also claimed that Taliban initiated 'unprovoked firing" in Torkham and Tirah. Both light and heavy weapons were used in skirmishes in Nazyan and Achin. An Afghan militant was killed during an infiltration attempt across the border in North Waziristan District. Pakistani military claimed to have killed 34 TTP militants in engagement throughout Khyber Pakhtunkhwa and Balochistan, with three killed in Lakki Marwat district, 10 killed in Bannu district and 13 killed in North Waziristan as well as eight killed in Zhob district. A police constable was killed in a militant attack in Wana while six police personnel including a DSP were killed and three were wounded in an insurgent ambush in Kohat District. An ex-Police officer and a militant were killed while another militant was injured in an engagement in Peshawar District.
On 25 February, local sources reported that further skirmishes took place in Maqbal area in Dand Aw Patan District of Paktia province between Taliban and Pakistani forces. Light clashes took place in Mohmand and Kurram Districts whereas heavy fighting occurred in Khyber District between Pakistani security forces and Pakistani Taliban. Pakistani military claimed to have killed 10 TTP militants in a follow-up operation in Zhob District. Unidentified militants attacked a police patrol in Bajaur killing four and wounding two police personnel and also killed a constable and his son in South Waziristan.
On 26 February, at around 20:00 local time (15:30 GMT), Taliban-led Afghanistan's officials announced the launch of what they described as a "retaliatory operation", directed by Defence Minister Mullah Yaqoob and Army Chief Fasihuddin Fitrat, along the border in the provinces of Nangarhar, Nuristan, Kunar, Khost, Paktia, and Paktika. As per the Taliban officials, 55 Pakistani soldiers were killed, and several others were captured. Taliban-led Afghanistan's officials further added that one military headquarters and 19 border outposts had been captured, while 4 border outposts were destroyed during the operation. Zabihullah Mujahid named seven of the border outposts that Taliban officials claimed to have captured. According to reports, the outposts were located inside Afghanistan, and it remained unclear how border outposts belonging to Pakistani forces were located on Afghan soil. At midnight local time (19:30 GMT), the Taliban-led Afghan Ministry of Defense announced the end of its four-hour operation. Pakistani officials rejected Taliban claims and stated that military action against Taliban forces was continuing. They further added that the attack had been repulsed, that the Taliban had suffered heavy losses, and that two Pakistani soldiers had been killed and three others were injured during the four-hour engagement.
In response to the Taliban's operation, Pakistan carried out air and ground strikes against Afghan Taliban positions in Kabul, Kandahar, Paktia, and Nangarhar. Faisal Karim Kundi, governor of Khyber Pakhtunkhwa, stated that the Afghan Taliban started the war and Pakistan will be the one to end it, while Khawaja Asif, Pakistan's defence minister, announced the start of an "open war" between the two countries. Pakistani officials stated that around 133 Taliban fighters were killed and more than 200 were injured during the clashes and subsequent operation. They further added that the airstrikes destroyed two corps headquarters, three brigade headquarters, two ammunition depots, one logistics base, three battalion headquarters, two sector headquarters, and more than 80 tanks, artillery pieces, and APCs (armoured personnel carriers). Pakistani officials also said that 27 border posts held by Taliban forces were destroyed and nine were captured. Taliban spokesperson Zabihullah Mujahid confirmed airstrikes in Kabul, Kandahar, Paktia, and several other locations, and stated that these airstrikes did not cause any casualties. The Taliban spokesperson also announced on X (formerly Twitter) that Taliban forces had responded to the airstrikes with attacks against Pakistani military positions in Kandahar and Helmand, two provinces in Afghanistan, although the post was later deleted.
