Pakistan said it intercepted four rudimentary drones launched from Afghanistan, while Afghanistan's Taliban government said it carried out air strikes inside Pakistani territory, marking the latest escalation in months of cross-border conflict between the neighboring countries.
The developments followed Pakistan's recent air attacks in eastern Afghanistan and a deadly militant attack in the Pakistani city of Karachi, further intensifying already strained relations between Islamabad and Kabul.
Both sides accused each other of supporting hostile armed groups and warned of further consequences if the confrontations continue.
Pakistan's military said its air defense network detected and neutralized four drones launched across the border into Balochistan by Afghan security forces.
The military said the drones were intercepted immediately and warned that continued provocations by the Afghan Taliban would receive a "befitting response."
The statement linked the drone launches to support for militant groups operating from Afghan-controlled territory.
The military did not report casualties from the intercepted drones.
However, Pakistan's Dawn newspaper, citing sources, reported that one woman was killed and six other people were injured in a suspected drone strike in Peshawar on Tuesday night.
Afghanistan's Defense Ministry said it carried out air strikes targeting alleged ISIS camps in Pakistan's Balochistan and Khyber Pakhtunkhwa provinces.
A ministry spokesperson said the strikes caused heavy casualties and material losses among the targeted group and were conducted with precision, resulting in no civilian casualties.
Pakistan, meanwhile, said its recent attacks inside Afghanistan targeted militants, while Afghan authorities said those strikes killed at least 36 civilians.
The latest exchange follows months of retaliatory military actions that have left hundreds of people dead in cross-border fighting since February.
Pakistan continues to accuse the Taliban government of sheltering the Pakistan Taliban (TTP) and other armed groups responsible for attacks inside Pakistan.
Afghan officials reject those allegations, instead accusing Pakistan of harboring hostile groups and violating Afghanistan's sovereignty.
The latest military exchanges underscore the continuing deterioration in relations as both governments maintain sharply conflicting accounts of the violence along their shared border.
