The Coast Guard sent a group of Cuban migrants intercepted off the coast of the Florida Keys back to their country Tuesday.

The group included three dozen Cuban nationals who were discovered headed for the U.S. last week.

Coast Guard Air Station Miami HC-144 Ocean Sentry aircrew initially discovered a migrant group on Friday and alerted nearby units, the Coast Guard said, according to a news release.

The crew of Cutter Issac Mayo then responded to the alert and found the migrants, per the statement.

"Our crews work tirelessly to ensure the South Florida Straits remain safe," said Lt. Paul Benyovszky, Coast Guard Sector Key West deputy enforcement chief.

"These migration attempts are inherently dangerous and these men, women, and children are taking a great risk attempting to navigate unpredictable seas in unsafe, overloaded, rustic vessels," the chief added.

The migrants were taken aboard the Coast Guard cutter and were provided food, water, shelter and basic medical attention before they were sent back to their own country, per the release.

This figure is an uptick from 838 Cuban migrants interdicted in Fiscal Year 2021, the first year of the Biden administration.

For context, just 49 Cuban migrants were interdicted in 2020, under President Donald Trump.
