Pakistan launched airstrikes and sent ground troops into Afghan provinces along its border on Sunday, killing dozens.

At least 36 civilians, including women and children, have been killed and more than 160 others wounded, says Afghanistan’s Taliban government, and has condemned it as a “cowardly act” and “a crime and atrocity”.

Pakistan’s information minister Attaullah Tarar said 29 militants were killed in strikes targeted at their hideouts, adding that the strikes were a response to “recent terrorist attacks against innocent people”.

Pakistan has long accused Afghanistan of harbouring terror groups that carry out cross-border attacks, a claim the Taliban government rejects.

Kabul, in turn, has previously accused Islamabad of carrying out unprovoked attacks in which civilians were killed – though Pakistan says it only targets militants.

The two countries had agreed to a ceasefire last October following weeks of deadly clashes. As with past internationally-mediated truce deals, however, that ceasefire has since fallen apart.

The BBC has not independently confirmed the casualty figures claimed by the Pakistani and Taliban governments in the latest attacks.

Afghanistan’s Taliban government says the strikes hit civilian homes, while Pakistan says they were targeted at militant hideouts in Afghanistan’s Paktia, Paktika and Kunar provinces.

Casualties were concentrated in Mandokhail, a village in the Paktika province, Taliban officials say.

The attacks on Sunday come a day after three members of the Sindh Rangers, a Pakistani paramilitary force, were killed at their headquarters in Karachi, according to Pakistan’s military. Three militants also died in the suicide attack, and Pakistani officials said they had arrested a fourth, who was an Afghan.

Jamaat-ul-Ahrar, a splinter faction of the TTP, claimed responsibility for Saturday’s attack.

Both the TTP, also known as the Pakistan Taliban, and Jamaat-ul-Ahrar are banned in Pakistan, and by the United Nations, because of their involvement in past attacks.

Intermittent border clashes and airstrikes in the border area have killed dozens of people in recent months, according to officials in both countries.

In February, clashes between the two countries left dozens of people dead. In March, a Pakistani strike on a drug rehabilitation centre in Kabul killed hundreds.

Earlier in June, Pakistan launched deadly air strikes that killed 26 militants. Afghanistan’s Taliban government said 13 people, mostly children, were also killed in the strikes.
