Last week, Pakistani drones struck targets inside the Afghan capital of Kabul and at a bazaar in Afghanistan’s Paktika province. The strikes targeted the Tehrik-e Taliban Pakistan terrorist group, with the TTP stating that two “important” members had been killed.

Prior to the drone strike, TTP members attacked and killed 11 Pakistani military personnel in northern Pakistan on Oct. 7. The Taliban’s retaliation for the Pakistani drone strikes began overnight on Saturday, with multiple small arms and artillery exchanges reported at posts along the border between Pakistan and Afghanistan. These are the deadliest exchanges between Kabul and Islamabad in years. Dozens have reportedly been killed in the clashes.
