Mortar and rocket attacks launched ‌by Pakistan against Afghanistan killed four people on Monday and injured 70 more, the Taliban government said, as fighting between the countries erupted again and threatened to derail fragile peace talks.

Pakistan's government dismissed the claims as a "blatant lie."

About 30 students, women, and children were among those injured ‌in the attacks, which targeted homes and the Syed Jamaluddin Afghani University ​in Kunar province's Asadabad, the Taliban's deputy spokesperson Hamdullah Fitrat said.

"We strongly condemn these attacks by the Pakistani military regime, in which ⁠ordinary people, academic, and educational institutions were targeted, and declare them unforgivable ​war crimes," he said in a post on X.

Pakistan's information ministry in a post ⁠on X said no strike had been carried out on the university. "The claims are frivolous and fake," it said.

The Pakistani military did not immediately respond to a request for comment.

The worst fighting in ‌years erupted between the allies-turned-foes in February, with Pakistani airstrikes inside Afghanistan that ​Islamabad said targeted ‌militant strongholds.

Islamabad has said Kabul provides safe haven to militants executing attacks on Pakistan from its soil. The ‌Taliban has denied the allegations and said militancy in Pakistan is an internal problem.

More than 400 people were killed in a Pakistani strike on a drug rehabilitation ⁠center in Kabul last month, the ‌Taliban had said, before the ⁠neigbours suspended fighting. Pakistan rejected the Taliban's statements, saying it "precisely targeted military installations and terrorist support infrastructure."

The United ⁠Nations ⁠Assistance Mission in Afghanistan had put the death toll at 143.

China, which was mediating between the countries, said earlier ‌this month that they had agreed during peace talks in Urumqi to explore a comprehensive solution to their conflict.

Skirmishes have died down since the talks in Urumqi were announced, ‌but there ​have been reports of ‌a few small clashes. Three people were killed in mortar shelling by Afghan forces on April 18 in Pakistan's northern Bajaur region, security officials said.
