Cuba confronts a US-registered speedboat amid infiltration claims and rising tensions
Cuba says its coastguard shot at a US-registered speedboat near Cayo Falcones, killing four and injuring six from a 10-person group; Cuba claims the passengers were armed Cubans in the US plotting infiltration and terrorism, with several detainees held. The United States is conducting its own investigation and says it is not a US-government operation, as tensions with Cuba mount amid fuel shortages and shifting oil-policy dynamics.
