A Taliban government spokesperson said on Monday that Pakistani airstrikes killed at least eight people, including three children, in border regions of Afghanistan.
Zabihullah Mujahid, a Taliban spokesperson, said Pakistani aircraft struck civilian homes in Khost and Paktika provinces near the border with Pakistan at around 3:00 a.m. local time (2230 GMT).
According to Mujahid, all eight people killed were women and children.
Pakistan's Foreign Office in Islamabad has also confirmed the strikes. They said that they targeted a splinter group of the Pakistani Taliban and described it as "intelligence-based anti-terrorist operations in the border regions inside Afghanistan."
The airstrikes targeted multiple suspected hideouts of Pakistani Taliban inside Afghanistan, two Pakistan security officials told AP. The Pakistani Taliban is a separate militant group but allied with the Afghan Taliban.
Mujahid condemned the airstrikes and warned that such a "violation of Afghanistan's sovereignty" would bring "bad consequences" beyond its neighbor's control.
In a separate statement, the Taliban's Defense Ministry said its security forces had targeted Pakistani troops on the border with heavy weapons later Monday in response to the airstrikes.
The Associated Press (AP) news agency reported, citing Pakistani officials, that Afghan Taliban's shots wounded four people and that some villagers in the northwestern Kurram district were moving to safer areas.
The officials added that Pakistan fired back, according to the AP report.
This is the latest escalation as tensions between Islamabad and Kabul simmer.
