Rare clash off island’s coast took place amid US oil embargo and heightened tensions between two countries

Cuban forces killed four exiles and wounded six others who sailed into its waters onboard a Florida-registered speedboat and opened fire on a Cuban patrol, the country’s government said, at a time of heightened tensions with the US.

Cuba’s interior ministry said the group comprised anti-government Cubans, some of whom were previously wanted for plotting attacks. They came from the US dressed in camouflage and armed with assault rifles, handguns, homemade explosives, ballistic vests and telescopic sights, it said.
