At least 9,000 undocumented immigrants, including British citizens, are to be sent to Guantanamo Bay detention camp, according to reports in the US.

The first transfers are due to start within days, as the Trump administration ramps up its campaign to deport illegal immigrants.

In January, Donald Trump announced plans to house 30,000 migrants in the notorious camp on Cuba, which was previously used as a military prison to house combatants captured during George W Bush’s “war on terror” following the September 11 attacks on the US.

According to documents seen by Politico,  the plan is to hold the migrants at the camp for a short period before deporting them back to their home country.

Guantanamo currently holds roughly 500 people.
