A suicide attack claimed by the Pakistani Taliban killed 16 soldiers and wounded more than two dozen people, including civilians, local government officials and police officers told AFP.
"A suicide bomber rammed an explosive-laden vehicle into a military convoy," said a local government official in North Waziristan district of Khyber Pakhtunkhwa province, who asked not to be named because he was not authorised to speak to the media.
He said 16 soldiers were killed, raising a previous death toll of 13.
"The explosion also caused the roofs of two houses to collapse, injuring six children," a police officer posted in the district told AFP.
The attack was claimed by the suicide bomber wing of the Hafiz Gul Bahadur armed group, a faction of the Pakistan Taliban.
Pakistan has witnessed a sharp rise in violence in its regions bordering Afghanistan since the Taliban returned to power in Kabul in 2021, with Islamabad accusing its western neighbour of allowing its soil to be used for attacks against Pakistan -- a claim the Taliban denies.
Around 290 people, mostly security officials, have been killed in attacks since the start of the year by armed groups fighting the government in both Khyber Pakhtunkhwa and Balochistan, according to an AFP tally.
