Cuban troops kill 4 in confrontation with Florida speedboat

Cuban border troops killed four people and wounded six during a confrontation Wednesday that Cuban authorities called an attempted terrorist attack, raising tensions with the U.S. during a politically fraught moment.

The island nation's Ministry of the Interior said the speedboat's passengers opened fire on troops after they approached the vessel in Cuban territorial waters.

A commander on the Cuban vessel was also wounded in the confrontation and the injured people from the speedboat were taken for medical treatment, the ministry said in a statement

In a statement later Wednesday, the Cuban government said the 10 people involved in the attack were Cuban nationals living in the U.S. who "intended to carry out an infiltration for terrorist purposes." Cuban authorities seized assault rifles, handguns and explosive devices following the confrontation.
