The United States has begun flying illegal immigrants down to Guantanamo Bay, Cuba.
Sources close to the matter told CNN the first military planes were set to depart on Tuesday.
Things have moved quickly since President Donald Trump announced the new policy on January 29.
According to CNN, almost immediately, US Marines flew down to assist with the construction of tents in which the inhabitants will stay during their time on the island. The Army is set to join them in the coming days to provide law enforcement, a feeding team, and a medical company.
Trump explained that the goal was to "detain the worst criminal illegal aliens threatening the American people," saying, "some of them are so bad we don't even trust the countries to hold them, because we don't want them coming back, so we're gonna send them out to Guantanamo."
He noted that the move would "double" the United States' capacity to detain and hold such people, calling Guantanamo, Cuba, a "tough place to get out of."
"Today's signings bring us one step closer to eradicating the scourge of migrant crime in our communities once and for all," Trump added, calling the situation the United States finds itself in evidence of an "unforced error."
Since its establishment in 2002, the facility at Guantanamo Bay has held some of the most notorious criminals, notably 14 al Qaeda terrorists.
They include Khalid Sheikh Mohammed, the mastermind behind the September 11 terrorist attacks, and his henchmen, Ramzi Binalshibh, Ali Abd al-Aziz Ali, and Mustafa Ahmad al-Hawasawi.
Other al-Qaeda terrorists brought to Guantanamo Bay are Aby Zubaydah, Walid bin Attash, Riduan bin Isomuddin, Ahmed Khalfan Ghalilani, Majid Khan, Abu Faraj al-Libi, Mohd Farik Bin Amin, Mohammed Nazir Bin Lep, and Gouled Hassan Dourad.
