The President of the USA, Donald Trump, has invoked an old war law from 1798, the Alien Enemies Act, to be able to deport undocumented migrants. The purpose is to speed up the deportation of members of the Venezuelan cartel Tren de Aragua, which Trump claims have "infiltrated" the country.
The law was last used by President Franklin D Roosevelt during World War II to intern and deport people of, among others, Japanese and German origin.
Since it is designed to be invoked when the USA is at war or threatened by invasion, experts believe it will meet resistance in American courts, reports CNN.
