"Cuba's vice foreign minister, Carlos Fernandez de Cossio, said Havana has launched "an investigative process aimed at clarifying the facts" after what it called a 'terror' incursion by 10 people arriving on a Florida-registered speedboat - an incident in which four of the group were killed, according to Cuban authorities. Fernandez said Cuban officials have been in contact with US counterparts - including the State Department and Coast Guard - since identifying the vessel as coming from US territory, and claimed the boat carried weapons and equipment, including 'assault rifles' and 'Molotov cocktails.' "As previously reported, among the items seized on the vessel were weapons, including assault rifles, sniper rifles, pistols, Molotov cocktails, multiple assault equipment, including night vision devices, bulletproof vests, assault bayonets, camouflage clothing, ammunition of various calibres, combat food supplies, communication devices and a significant number of monograms of counterrevolutionary organisations of a terrorist nature. This information remains preliminary," said the senior official. On Wednesday, the US said it was gathering information to find whether the victims were American citizens or permanent residents. The vice minister also claimed that the event "is not an isolated act," but rather a sign of the aggressions Cuba has suffered for decades. "Cuba has been the victim of aggressions and countless terrorist acts for more than 60 years, mostly organised, financed and carried out from United States territory," Fernandez declared. He also added that the country's authorities are "willing to engage with the US government regarding this event." "Among other requests, we will seek information about those involved, the means used and other details from US authorities through the mechanisms in force between the two countries," said the senior official. On Wednesday, the Cuban Interior Ministry reported that a boat flying a US flag had entered Cuban territorial waters and opened fire, prompting border guards to respond. It added that the crew consisted of Cubans living in the United States who intended to enter Cuba for 'terrorist' purposes. US Secretary of State Marco Rubio said his country was investigating the 'highly unusual' incident."
