See it on the Geopolitics map →The picture
Pakistan says the Pakistani Taliban (TTP), who killed hundreds of its soldiers and police in 2024–25, shelter in Afghanistan; the Taliban deny it. Pakistani strikes on Kabul in October 2025 set off border battles and a Qatar- and Turkey-brokered truce that soon frayed. After Afghan attacks on border posts, Pakistan bombed Kabul, Kandahar and Paktika on February 27, 2026, and its defense minister declared 'open war'. China-hosted talks in April made little progress; strikes flared again in September 2026.
Why it matters
It pits former patrons against their protégés, cuts trade and uproots refugees, and opens a second hot front for nuclear-armed Pakistan.
Key facts and numbers
Both governments' statements, UN casualty and displacement reports, and wire-service reporting; each side's battle-death claims far exceed what the other admits.
What to watch
Whether the Taliban can or will rein in the TTP, and whether China's mediation can produce a lasting deal.

▸Pakistan struck Kabul in Pakistan–Afghanistan border warFact
The relationship
Accusing the Taliban of sheltering Pakistani Taliban (TTP) fighters, Pakistan struck Kabul in October 2025, reportedly targeting TTP leader Noor Wali Mehsud. After Afghan attacks on its border posts, it bombed Kabul, Kandahar and Paktika in February 2026 and declared 'open war'.
Since when and why
Strikes on October 9, 2025 and February 27, 2026 (Pakistan's 'Operation Ghazab lil-Haq'); 'open war' declared by Defense Minister Khawaja Asif.
How we know
Pakistani official statements, Taliban condemnations of the strikes, UN reports of civilian deaths, and wire-service reporting from both capitals.
What to watch
Disputed casualty claims: Pakistan says it killed hundreds of Taliban fighters; Kabul admits far fewer and highlights civilian deaths.
▸Pakistan–Afghanistan border war pits Pakistan against Afghanistan under the TalibanFact
The relationship
The war sets Pakistan against the Taliban it once sheltered and backed. At issue are TTP militants based in Afghanistan and the 2,600 km Durand Line, a colonial-era border no Afghan government, the Taliban included, has accepted. Pakistan has shut crossings such as Torkham and pushed out hundreds of thousands of Afghan refugees.
Since when and why
Along the Khyber Pakhtunkhwa and Balochistan borders since October 2025; mediation by Qatar and Turkey (October 2025) and China (Urumqi, April 2026).
How we know
UN reports on civilian casualties and displacement, official statements, and border-closure and trade data.
What to watch
Whether the Durand Line dispute can ever be settled, and whether Pakistan's pressure weakens Taliban rule or rallies Afghans behind it.
