The comments come after the Taliban administration blamed Pakistan for airstrikes that officials say killed dozens in Kunar and Khost provinces.

Pakistan, which has not confirmed any involvement in airstrikes inside Afghanistan’s borders, said the two countries are “brotherly countries”.

“We are facing problems and challenges from both the world and our neighbors, the clear example is invasion by them in our territory in Kunar,” said Mullah Mohammad Yaqoob, acting Afghan defence minister, at a ceremony in Kabul commemorating the anniversary of the death of his father, Taliban founder Mullah Mohammad Omar.

“We can’t tolerate the invasion. We have tolerated that attack. We tolerated that because of national interests, next time we might not tolerate it,” he said.

Pakistan’s foreign office spokesperson said when asked for comment on Yaqoob’s comments that Pakistan hoped for longterm engagement with Afghanistan to secure peace.

“Pakistan and Afghanistan are brotherly countries. The governments and people of both countries regard terrorism as a serious threat and have suffered from this scourge for long time … therefore, it is important that our two countries engage in a meaningful manner through relevant institutional channels to cooperate in countering cross border terrorism and taking actions against terrorist groups on their soil,” the spokesperson said.

The Taliban administration’s foreign ministry last week called in Pakistan’s ambassador to protest against the strikes. Local officials said the strikes by Pakistan military helicopters killed 36 people.

The United Nation’s children’s agency head in Afghanistan said that 20 children were killed in airstrikes in Khost and Kunar on April 16.

Since the Taliban took over Afghanistan in August, there have been numerous standoffs along the 2,600-km (1,615-mile) border with Pakistan - drawn by British colonial rulers and disputed by Kabul.

Increasingly frustrated by continuing militant attacks, Pakistan’s military has stepped up operations along the Afghan border in recent months.
