Pakistan bombed Taliban government targets in Afghanistan's major cities overnight, officials from both countries said on Friday, with Pakistan's defense minister calling the conflict "open war.”
Security sources in Pakistan said the strikes involved air-to-ground missile attacks on Taliban military offices and posts in Kabul, Kandahar and Paktia as well as ground clashes in multiple sectors along the border between the two nations.
The Taliban said it launched what it described as retaliatory attacks on Pakistani military installations.

Both sides reported heavy losses, issuing sharply differing figures that Reuters could not independently verify.
"Our cup of patience has overflowed. Now it is open war between us and you (Afghanistan)," Pakistani Defense Minister Khawaja Muhammad Asif said on Friday.
Relations between Kabul and Islamabad have been strained by a long-running dispute over Pakistan's accusation that Afghanistan harbors militants carrying out attacks across the border. The Taliban have denied the charge and said Pakistan's security is an internal problem.

The strikes on Taliban government installations are a major escalation, and threaten a protracted conflict along the 2,600-km (1,615-mile) frontier.
Taliban spokesperson Zabihullah Mujahid confirmed Pakistani forces carried out air strikes in parts of Kabul, Kandahar and Paktia but did not give details.
Kandahar is the headquarters of the Taliban and the city where supreme spiritual leader Haibatullah Akhundzada is based.
Video shared by Pakistani security officials showed flashes of light in the night from firing along the border and the sound of heavy artillery. A video of strikes on Kabul, for which Reuters was able to verify the location, showed thick plumes of black smoke rising from two sites and a massive blaze in part of the capital.
Another video showed a building on fire, which the officials said was a Taliban headquarters in Paktia province.
"Pakistani counter-strikes against targets in Afghanistan continue," a Pakistani government spokesperson, Mosharraf Zaidi, said in a post on X, describing the action as a response to "unprovoked Afghan attacks."
Reuters witnesses in Kabul said many ambulance sirens could be heard following loud blasts and the sound of jets.
Zaidi said 133 Afghan Taliban fighters were killed and more than 200 wounded, with 27 posts destroyed and nine captured.
Mujahid, the Taliban spokesperson, said 55 Pakistani soldiers were killed and 19 posts seized, while eight Taliban fighters were killed, 11 wounded and 13 civilians injured in Nangarhar province.
