By Ted Hesson WASHINGTON (Reuters) -A U.S. civil rights group on Saturday sued to block the Trump administration from potentially transferring 10 migrants from the U.S. to a naval base in Guantanamo Bay,

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

Civil rights attorneys sued the Trump administration Saturday to prevent it from transferring 10 migrants detained in the U.S. to Guantanamo Bay, Cuba, their second legal challenge in less than a month over plans for holding up to 30,

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