The Cuban government said Wednesday that 10 people aboard a Florida-registered speedboat that entered Cuban waters and opened fire on a Cuban patrol were armed with assault rifles and had "terrorist" intentions, according to official media.

The occupants of the speedboat were Cubans who resided in the U.S., state-run news outlet Cubadebate reported, citing the interior ministry.

Cuba said earlier that its forces killed four people and wounded six others aboard the speedboat.
