Firefights broke out along the Pakistan-Afghanistan border late on Saturday, with the Afghan Taliban attacking Pakistani posts, according to security officials from both countries, following a Pakistani air strike in Kabul this week.

Pakistani security officials said that they were responding “with full force” to what they called unprovoked firing from Afghanistan. The exchange of fire took place at more than six locations along the border, they said.

The Taliban forces said they captured three Pakistani border posts. Pakistani security officials said their military had destroyed several Afghan posts.

Video footage shared by Pakistani security officials showed gun and artillery firing towards Afghanistan, lighting up the night sky.

Enayatullah Khowarazmi, spokesman for Afghanistan’s Ministry of Defence, said it was a retaliatory operation for Pakistan’s violation of Afghan airspace. He said the attack concluded at midnight local time.

“If the opposing side again violates Afghanistan’s airspace, our armed forces are prepared to defend their airspace and will deliver a strong response,” Khowarazmi said.
