Pakistan's Foreign Minister Jalil Abbas Jilani has defended his country's decision to deport all illegal immigrants, including 1.73 million Afghans.

Jilani said Thursday that no other country allows illegal immigrants and the decision is in line with international practice.

The order, announced on Tuesday and with a Nov. 1 deadline for people to go, has frayed Islamabad's relations with Afghanistan's ruling Taliban, who said the threat to force out Afghan migrants was "unacceptable."

"No country allows illegal people to live in their country, whether it is Europe, whether it is countries in Asia, in our neighborhood," the minister in a caretaker Pakistani government, Jilani, told Hong Kong's Phoenix TV in an interview on the sidelines of a forum in Tibet.

"So, accordingly, this is in line with the international practice that we have taken this decision."

Pakistan has been a refuge for people fleeing from war in Afghanistan since the 1970s.

Pakistan's Interior Minister said Tuesday some 1.73 million Afghans in Pakistan had no legal documents and the number of Afghan refugees in Pakistan totaled 4.4 million.

In defending the decision to expel Afghans, Pakistani authorities said 14 of 24 suicide bombings this year had been carried out by Afghan nationals. A Taliban spokesman rejected that assertion.

"Whenever there was any problem, people would immigrate to Pakistan, take refuge in Pakistan," Jilani said.

"But now I think it has been more than 40 years, so the government of Pakistan has taken a decision," Jilani said, noting that the situation in Afghanistan had stabilized.

Decades of war in Afghanistan largely ended in mid-2021 when the Taliban retook control as U.S.-led foreign forces were withdrawing and a U.S.-backed government collapsed.

While Pakistan has for years favored the Taliban as Pakistan's best option in its neighbor, relations have deteriorated over the past couple of years, largely over Pakistani accusations that terrorists fighting the Pakistani state operate from Afghan territory.

The Taliban deny that.

Jilani said Pakistan had been discussing the migrant issue with Afghanistan "for a very long time" and he called on international humanitarian agencies to help with the process.

Aid officials say Afghanistan is already facing a humanitarian crisis and the forced repatriation of large numbers of people would compound dire problems.
