Afghan Taliban spokesman Zabihullah Mujahid said Pakistani forces carried out attacks in Spin Boldak district of Afghanistan’s Kandahar province.
A spokesman for Pakistan’s prime minister accused Afghan forces of “unprovoked firing” along the Chaman border.
“Pakistan remains fully alert and committed to ensuring its territorial integrity and the safety of our citizens,” spokesman Mosharraf Zaidi said in a statement.
The cross-border exchange occurred two days after a new round of peace negotiations between the neighboring states ended without a breakthrough, though both sides reaffirmed their fragile ceasefire.
In a related development, the recent talks in Saudi Arabia followed earlier sessions hosted by Qatar, Turkey and Saudi Arabia, all aimed at easing tensions that spiked after deadly clashes in October.
At the center of the dispute, Pakistan says militants based in Afghanistan have conducted recent attacks on its soil, including suicide bombings involving Afghan nationals.
Kabul rejects the allegation, arguing it cannot be held accountable for security incidents inside Pakistan.
Dozens of people were killed in the October violence, the most serious border fighting since the Taliban seized power in Afghanistan in 2021.
