Pak-Afghan hostilities flare up again

The information ministry of Pakistan on Monday said military conducted airstrikes on terrorist sites “in the border region with Afghanistan”, killing more than alleged 28 terrorists. 
A security official said two Afghan provinces were also targeted. Afghan Taliban officials accused Islamabad of killing at least three civilians in overnight airstrikes on its territory.
The attacks broke nearly three months of relative calm.
Zabihullah Mujahid, chief spokesperson of the Taliban-run Afghan government, said the Afghan side "will respond appropriately to this aggression."
A Pakistani official, speaking on condition of anonymity, said the strikes happened in the Afghan provinces of Paktika and Kunar. Pakistan's Information Ministry gave the death toll but its military did not immediately comment.
Relations between the former allies have been strained for years, with Islamabad accusing Kabul of harbouring militants who stage cross-border attacks. Conflict escalated this February and hundreds died in airstrikes, drone attacks, and artillery fire in the first half of the year.
Afghanistan's Taliban government denies harbouring anti-Pakistani insurgents and says militancy is Pakistan's internal problem.
