Pakistan has carried out a series of air strikes inside Afghanistan, killing at least 15 people, according to Afghan officials. The attack, which took place in the early hours of this morning, targeted what Islamabad claims were militant hideouts in the border provinces of Khost and Kunar. Afghan authorities have condemned the incursion, calling it a violation of sovereignty.
Whitehall is rattled. The Foreign Office has issued a carefully worded statement urging both sides to "exercise restraint and pursue dialogue." Privately, officials admit this is a dangerous escalation. Pakistan's gamble is clear: a show of strength against the Taliban-backed groups it accuses of harbouring anti-Pakistan militants. But the risk of a wider conflagration is high.
The timing is awkward. British diplomats have been working behind the scenes to stabilise the region after the chaotic US withdrawal. This strike undermines those efforts. Sources tell me the PM's national security adviser has already spoken to his counterpart in Islamabad. The message was blunt: a full-scale border conflict is in no one's interest.
Labour is circling. Shadow Foreign Secretary David Lammy has demanded an immediate Commons statement. Backbenchers on both sides are uneasy. The usual coalition of the bilious and the bleeding-heart is forming. Expect questions about UK complicity. Did we know? Did we give the green light? The answer, I'm told, is no. But in the febrile atmosphere of Westminster, that won't satisfy the conspiracy theorists.
The numbers game: Afghanistan has summoned the Pakistani ambassador. The Taliban has warned of retaliation. Pakistan's military is on high alert. The coming hours are critical. This could blow over. Or it could be the spark that lights a regional powder keg.
What Whitehall wants: A hotline between the two militaries. A cooling-off period. Public condemnation tempered with private diplomacy. It's a delicate dance. The UK has influence with both sides, but not control. The question is whether Pakistan's leadership feels cornered enough to double down.
My source on the Foreign Affairs Select Committee says the mood is grim. Memories of the 1990s, when Pakistani support for the Taliban fuelled a civil war, are fresh. The fear is that we are sleepwalking into a repeat. Except this time, the players are armed with drones and precision missiles.
Watch for: A UN Security Council emergency session. Blinken's phone call to Islamabad. The first casualty reports from the ground. And the reaction in Karachi and Peshawar. This story has legs. It's going to be a long day at the news desk.
