If you’ve followed the news this week, you know Pakistan and Afghanistan are on edge again. Early on Monday, September 21, 2026, Pakistani jets struck targets inside eastern Afghanistan. That single night broke a fragile calm that had held for months. In this article, I’ll explain what happened, why it matters, and what could come next. I’ll keep it simple and stick to facts from trusted sources like AP, Reuters, and the United Nations. What Happened in the Latest Airstrikes Afghan officials say the strikes hit Nurgal district in Kunar province and Barmal district in Paktika province at around 3 a.m. The two sides tell very different stories about the results. Pakistani security officials say the jets hit militant hideouts and killed 28 suspected fighters, while Kabul says three civilians died and four others were wounded. Here’s the catch. Neither side’s numbers have been independently verified. That’s common in the first days of any conflict, so treat early figures with care. Afghan officials also said one home in Kunar was destroyed, killing a villager and two family members. In Paktika, a shop and an empty house were hit, but no one was hurt. Taliban government spokesman Zabiullah Mujahid condemned the strikes and promised a response. Reuters reported that the attack threatens to reignite tensions after nearly three months of relative calm. Arab Why Pakistan Struck: The Attacks That Came First Pakistan says the strikes didn’t come out of nowhere. Violence had already hit its northwest hard. On Friday, a suicide bomber attacked a mosque inside a police compound in Kohat, and eight gunmen stormed nearby offices. The fight lasted about 20 hours. At least 21 people died, mostly police officers, and more than 100 were wounded. On Saturday, Pakistan’s Information Ministry warned that it could strike militants inside Afghanistan. A day later, six security personnel, including two army officers, were killed in a shootout in Hangu. Then the jets flew. Pakistan blames militants it says are based in Afghanistan, and it accuses the Afghan Taliban government of sheltering them. It wants Kabul to take credible, provable, and lasting steps to shut down their camps and training networks. Who’s behind the attacks? No group had claimed the Kohat or Hangu attacks when the strikes happened, but suspicion fell on the Pakistani Taliban, known as the TTP. It helps to know the difference between the two groups. The TTP is separate from the Afghan Taliban but allied with them. The Afghan Taliban deny the charges and say militancy is Pakistan’s own internal problem. How We Got Here: A Short Timeline This crisis didn’t start last week. Here’s a quick look at the key moments over the past year. Date What Happened October 2025 Pakistani air strikes set off the deadliest clash between the two countries since the Taliban takeover, and Qatar and Turkey brokered a temporary ceasefire. Late 2025 Saudi-mediated talks collapsed and cross-border violence resumed. February 22, 2026 Pakistan carried out air strikes on alleged militant camps. February 26, 2026 Afghan Taliban forces attacked Pakistani army posts. February 27, 2026 Pakistan’s defense minister announced “open war” with the Taliban. April 2026 Peace talks began in the Chinese city of Urumqi. September 21, 2026 New Pakistani airstrikes hit Kunar and Paktika. The February round was the scariest so far. It followed a suicide bombing at a mosque in Islamabad on February 6 and a TTP assault in Bajaur on February 17. Pakistan then hit major cities, including Kabul and Kandahar, as well as Bagram airbase, and Kabul answered by targeting Pakistani military sites. After that, Monday’s strikes on border provinces look small, but they show the old problem is still alive. What Each Side Is Saying When two governments give two different versions of the same night, it’s easy to get lost. This simple comparison shows where they disagree. Topic Pakistan’s Position Afghan Taliban’s Position The militants Says the TTP and allied groups plan attacks from Afghan soil. Denies sheltering them and calls militancy Pakistan’s internal problem. The airstrikes Says they hit hideouts and killed 28 suspected militants. Says three civilians died and calls the strikes aggression. The way forward Wants credible, verifiable, and sustained action against militant sanctuaries. Says Pakistan is trying to distract from its own security failures and promises a response. Notice how neither side is talking past a shared fact. They don’t agree on who was hit, who is hiding whom, or who is to blame. That’s why outside checks, like UN monitoring, matter so much. The Human Cost for Ordinary Families Behind every headline are real people. The United Nations tracked the toll earlier this year. Its mission in Afghanistan reported more than 370 Afghans killed in the first three months of 2026, a higher figure for that period than it has recorded since 2011. The UN humanitarian office also said the conflict had displaced 94,000 people, and 100,000 people in two border districts were completely cut off by the fighting. Pakistan pays a price too. Militant attacks on its police and security forces have surged in recent years. Every funeral of a police officer adds pressure on leaders in Islamabad to respond. And every airstrike that kills a civilian adds anger on the Afghan side. That’s how this cycle keeps feeding itself. Border Closures, Trade, and Deportations You may not live near the border, but you can still feel these tensions in the economy. Torkham has been closed to trade and regular travel since February, and it now mostly serves the deportation of undocumented Afghans. Roughly 1,000 to 1,500 people are sent back through it each day. That’s a big deal for a crossing that used to move goods worth millions. Amu TV The human side is heavy. Refugees International says more than 146,000 Afghans were deported from Pakistan in the first months of 2026, on top of over one million in 2025. Many of these families arrive in Afghanistan with almost nothing. Meanwhile, traders on the Pakistani side are losing patience. They have threatened
