Word from the Cuban government of a deadly encounter between its troops and a boat carrying armed expatriates is casting a spotlight on Cubans living in the U.S. who still harbor aspirations of a counter-revolution 67 years after a guerrilla uprising ushered in communism.

Cuban soldiers confronted a speedboat carrying 10 people as the vessel approached the island and opened fire on the troops, who fired back.

Cuba says the 10 passengers on a boat that opened fire on its soldiers were armed Cubans living in the U.S. who were trying to infiltrate the island and unleash terrorism.
