Authorities have stepped up arrests of Afghan citizens in Pakistan's capital and a nearby city in an effort that the Afghan Embassy in Islamabad described on Wednesday as a push to force the expulsion of all Afghan refugees from the country.

Afghan refugees are facing arrests and harassment in Pakistan as part of a mass expulsion campaign, Kabul's embassy in Islamabad said on Wednesday, after the U.N.'s refugee agency said hundreds had been expelled from two cities.

The Afghan embassy in Islamabad says Pakistan wants to remove all Afghan refugees from the country and they face expulsion in the near future

Diplomats from Afghanistan’s ruling Taliban reported Wednesday that neighboring Pakistan is implementing a plan for the “imminent” and swift mass deportation of nearly three million Afghan refugees from its territory.

The Afghan embassy in Islamabad has warned that Pakistan is preparing to expel all Afghan refugees, with arrests and forced relocations already underway in the capital and Rawalpindi, according to a report in Associate Press.
