The lawsuit says there is no legitimate reason to send migrants to Guantánamo because the U.S. has ample detention facility.

The American Civil Liberties Union (ACLU), the Center for Constitutional Rights, the International Refugee Assistance Project (IRAP), and the ACLU of the District of Columbia filed a lawsuit on behalf of migrants who face the risk of being transferred to Guantánamo Bay.

The new case, which for now is asking for a court to block the transfer of 10 men to the offshore base, is the first to directly challenge the policy.

The individuals at risk of detention at Guantanamo Bay include seven Venezuelan nationals, one Afghan national, one Pakistani national and one Bangladeshi national.

Civil rights attorneys are suing the Trump administration to prevent it from transferring 10 migrants detained in the U.S. to Guantanamo Bay, Cuba

The base had been cleared of migrants since Thursday, after the government sent 177 to Venezuela and one back to the United States.

Civil rights attorneys sued the Trump administration Saturday to prevent it from transferring 10 migrants detained in the U.S. to Guantanamo Bay, Cuba, and filed statements from men held there who said they were mistreated there in conditions that of one of them called ''a living hell.
