Taliban and Pakistani security forces exchanged fire along the after Pakistani soldiers tried to erect a military structure on the Afghan-Pakistani border, causing multiple casualties on both sides, the Taliban said on Wednesday.
The Pakistani military said its forces had responded to cross-border fire from militants, and that three of its soldiers were killed.
The border was drawn up decades ago during British colonial rule and long been disputed, often leading to clashes. Pakistan treats it as an international frontier and has fenced it, while Afghan authorities do not recognise the demarcation.
"Pakistan forces tried to erect a military post near the line," Taliban spokesman Bilal Karimi said, adding that this was against the "rules" and Pakistani forces had opened fire when Taliban forces approached the construction.
