Venezuelan President Nicolás Maduro has strongly criticised the deportation of hundreds of Venezuelan immigrants from the United States to an El Salvador mega-prison. Venezuela's government has compared the deportations to Nazi concentration camps. "Is this legal, is it fair, is it human, Nayib Bukele? Is it human to do this to a human being just because it is a Venezuelan migrant or because it has a tattoo?" Maduro asked on Monday evening. The arrival of the immigrants, alleged by the US to be members of the Venezuelan Tren de Aragua gang, took place under an agreement for which the Trump administration will pay the government of President Nayib Bukele $6 million for one year of services. US President Donald Trump invoked the Alien Enemies Act for the first time since World War II, using the sweeping powers of a centuries-old wartime law to target alleged members of a Venezuelan gang. The deportations over the weekend came as a federal judge issued an order temporarily barring them. “These Venezuelan migrants who were kidnapped, who were not given the right to defence, who are labelled as murderers as terrorists, staining their honour and dignity, who were put in a concentration camp in El Salvador, have the right to defence and I will not rest until we achieve their rescue and their safe return to Venezuela, we will not rest.” ... “Is this legal, is it fair, is it human, Nayib Bukele? Is it human to do this to a human being just because it is a Venezuelan migrant or because it has a tattoo?” ... "To carry them in handcuffs, to hit them in the runway, to hit them when they entered (the prison), why do they hit them, why do they humiliate them? That happens, Why? Why do they have to cut their hair? This is kidnapping, concentration camp, humiliation, violations of national and international laws and besides, slave work, as a cherry on top. Are we back to times of slavery? For the love of god."
