The photographs, shared by Homeland Security Secretary Kristi Noem, show a group of people wearing grey uniforms and handcuffed hands, escorted by security agents.

One image shows a man with neck tattoos being held by a military officer. Another image shows a migrant with a serious expression walking alongside a hooded officer dressed in a camouflaged uniform. The scene takes place on what appears to be an airstrip, with buses and official vehicles in the background.

In a message posted on the social networking site X, Noem said: «President Trump has been very clear: Guantánamo Bay will house the worst of the worst. That starts today. Less than a week ago, Trump had announced the construction of a new detention centre at Guantánamo Bay Naval Base, with the capacity to hold up to 30,000 migrants.
