SAN JOSÉ, Costa Rica (AP) — Cuban soldiers confronted a speedboat carrying 10 people as the vessel approached the island and opened fire on the troops, who fired back, killing four and wounding six, according to the Cuban government.

The Cuban Ministry of the Interior said the people aboard the boat Wednesday were Cubans living in the U.S. and accused them of trying to infiltrate the country to engage in terrorism. U.S. Secretary of State Marco Rubio said it was not a U.S. government operation.

Here’s what to know about the confrontation that has resulted in investigations in both Cuba and the United States and could add to tensions between the two countries.
