Afghan deportation via Pakistan drew a firm response from Kabul on Monday after reports that more than 150 Afghans in the US may be sent for onward return.
Taliban authorities on Monday voiced serious concern over reported US plans to deport Afghans via Pakistan.
More than 150 Afghans in the United States would be moved through Pakistan for eventual return to Afghanistan, according to US media reports and an advocacy group.
Foreign ministry spokesman Abdul Qahar Balkhi said those involved had not obtained legal residency documents in Pakistan.
Advocacy groups warned that removing former US allies and their families could put lives at risk.
The United Nations has recorded reports of extrajudicial killings, detentions and abuses in Afghanistan despite Taliban amnesty pledges.
