Cuba's government said Wednesday that its soldiers killed four people aboard a speedboat registered in Florida that opened fire on officers in Cuban waters.

Cuba's Interior Ministry issued a statement that provided few details about the shooting but noted that the boat was roughly 1 mile northeast of Cayo Falcones, off Cuba's north coast.

It was unclear if any U.S. citizens were aboard.

The government provided the boat's registration number, but The Associated Press was unable to readily verify details of the boat because boat registrations are not public in the state of Florida.

Officials said one Cuban officer was injured, four suspects were killed, and six others were injured.

It wasn't immediately known what the boat and its occupants were doing in Cuban waters.

In the statement, the ministry said Cuba's government was "safeguarding its sovereignty and ensuring stability in the region."

James Uthmeier, Florida's attorney general, said he has ordered prosecutors to work with federal, state, and law enforcement partners to start an investigation.

"The Cuban government cannot be trusted, and we will do everything in our power to hold these communists accountable," he wrote on X.

Meanwhile, Rep. Carlos A. Gimenez, R-Fla., decried the four killings and accused the Cuban government of murder.

"This regime must be relegated to the dust bin [sic] of history!" he wrote on X.

It's not unusual for skirmishes to erupt between Cuba's Coast Guard and U.S.-flagged speedboats in Cuban waters, but there have been no recent reports of passengers opening fire or being killed.

In past years, some of those U.S.-flagged boats were laden with unidentified items headed toward the island or they were going to pick up Cubans and smuggle them into the U.S.

Officials with the U.S. Coast Guard, the Department of Homeland Security, and the White House did not immediately respond to requests for comment.

The Pentagon declined comment and directed questions to the State Department, which did not immediately respond to a message seeking comment.

The incident comes as tensions simmer between the U.S. and Cuba in the wake of mounting pressure by the Trump administration. The two countries used to collaborate on drug smuggling and other crimes but have since stopped doing so.
