Pakistan's defence minister has said the country is in "open war" with Afghanistan, after Islamabad launched airstrikes on Kabul as part of a wave of attacks across the country.
"Our patience has now run out," said Khawaja Muhammad Asif following the attacks.
The strikes came after the Afghan Taliban announced a major offensive against Pakistani military posts near the border on Thursday night.
The latest attacks follow months of clashes between the two neighbouring nations, despite agreeing to a fragile ceasefire in October.
Last year's negotiations failed to reach a broader agreement for a complete end to hostilities, with both side blaming each other for not engaging seriously with talks.
