Trump announces Guantanamo Bay base expansion to detain up to 30,000 migrants
The project has caused indignation in Cuba, which claims sovereignty over the base, occupied more than 100 years ago by the US military, writes PABLO MERIGUET

ON JANUARY 29, the White House directed the Defence and Homeland Security Departments to expand the capacity at the Guantanamo Bay Naval Base in order to receive 30,000 migrant detainees.
In a press conference the following day, President Donald Trump cited his distrust in the nations of origin to reliably accept the forced return of their migrants, as a key factor in the expansion of Guantanamo Bay.
Cuba has strongly condemned Trump’s decision, criticising the US presence on Guantanamo Bay entirely, which it considers an illegal occupation. The base has historically detained refugees, and more recently, alleged terrorists without formal charges.
