American authorities are violating human rights and international norms by questioning the Iranian nationals or ethnic Iranians on the border, Iranian Foreign Ministry Spokesman Seyed Abbas Mousavi said.

He condemned the US Customs and Border Protection’s recent illegal and inhumane treatment of Iranian nationals and citizens, Tasnim agency reported.

“Such absolutely discriminatory measures that are taken only because of the race, nationality or maybe the faith of people are totally rejected in terms of international human rights laws and principles, and would result in accountability for the US government,” he added.

According to CNN, dozens of American citizens of Iranian descent were stopped at a port of entry in Blaine, Washington, in the days following the January 3 assassination of General Soleimani. Some were detained for hours and reported they were asked detailed questions about their country of birth.
