Clashes erupted between Pakistani and Afghan forces in a remote northwestern border region. State-run media in Pakistan accuse Afghan troops of opening “unprovoked fire."

Pakistani forces responded on Tuesday, damaging Afghan tanks and military posts, according to Pakistan TV and two security officials who spoke on condition of anonymity because they were not authorized to speak to the media.

A deputy police spokesperson in Afghanistan’s Khost province confirmed the clashes but provided no further details.

This is the second time this week that Pakistan and Afghanistan have traded fire along their long border.

According to Pakistan’s state-run media, Afghan forces and Pakistani Taliban jointly opened fire at a Pakistani post “without provocation,” prompting what the media described as a “strong response” from Pakistani troops in Kurram, a district in Khyber Pakhtunkhwa province.

Security officials said Pakistan's military also destroyed a sprawling training facility of the Pakistani Taliban.

There was no immediate comment from Pakistan’s military, which has been on high alert since Saturday, when both sides traded fire across multiple border regions, resulting in dozens of casualties on each side.

Although the clashes halted on Sunday after appeals from Saudi Arabia and Qatar, all border crossings between Pakistan and Afghanistan remained closed.
