At least nine children and a woman were killed after Pakistani forces bombed the home of a local resident in Afghanistan's Khost province, Afghan Taliban spokesman Zabihullah Mujahid said.
Mr Mujahid said Pakistan also carried out raids in the provinces of Kunar and Paktika, injuring four civilians.
"Last night at 12 o'clock in the Gerbzwo district of Khawstprovince, Pakistani invading forces bombed the house of civilian local resident Wilayat Khan, which martyred nine children (five boys and four girls) and one woman, and destroyed their house," Mr Mujahid said in a post on X, accompanied by pictures of the dead.
The Pakistan military and foreign ministry could not be reached for comment outside business hours.
The bombardment follows an unclaimed suicide bomb attack yesterday against Pakistan security forces in a province bordering Afghanistan.
Another blast in the Pakistan capital Islamabad this month killed 12 people and was claimed by the Pakistan Taliban, which shares the same ideology as the Afghan Taliban.
The Pakistani and Afghan militaries clashed in October, killing dozens, in the worst violence since the Taliban returned to power in Afghanistan in 2021.
Both sides signed a ceasefire in Doha in last month, but peace talks in Turkey collapsed without a long-term deal due to a disagreement over militant groups hostile to Pakistan that operate inside Afghanistan.
