Caribbean U.S. warns citizens not to travel to Cuba By Associated Press / September 29, 2017 Share 1 -- WASHINGTON (AP) -- The United States has issued an official travel warning that urges American citizens not to visit Cuba. Numerous workers at the U.S. Embassy in Havana have been targeted in "health attacks." The State Department warning says attacks occurred in residences and hotels that Americans frequently visit. The State Department says it believes U.S. citizens may be at risk if they visit, even if they aren't diplomats.The travel warning says that symptoms experienced by those affected by the attacks include hearing loss, cognitive issues, trouble sleeping, fatigue, headache, dizziness and ear complaints.The U.S. is also warning citizens that the government will have limited ability to help them if they travel to Cuba. That's because the U.S. is withdrawing most of its diplomats in Cuba in response to the attacks.Republican Sen. Tom Cotton of Arkansas said the State Department's decision to withdraw large numbers of its staff from the U.S. embassy in Havana demonstrates just how "untrustworthy and malicious" the Cuban government is. He also is criticizing former President Barack Obama for seeking to normalize ties between the two former Cold War rivals. The United States and Cuba reopened embassies in Washington and Havana in 2015 after a half-century of estrangement.Cotton says it was "foolish of Obama to open his arms to such a brutal, Marxist regime."Cotton says the Trump administration should expel accredited Cuban diplomats from the United States.Secretary of State Rex Tillerson says the U.S. embassy in Havana will keep only emergency personnel working there until Cuba can ensure the U.S. that its diplomats are safe. Tillerson said in a statement that the decision to pull out roughly 60% of the embassy staff was "to ensure the safety of our personnel."He says the U.S. continues to have diplomatic relations with Cuba that advance U.S. interests and national security. Tillerson says the U.S. will continue cooperating with Cuba on the investigation.The secretary says the U.S. has no reports that private American citizens were affected by the attacks. But he says that because the U.S. doesn't know the cause or source of the attacks, it can't advise people on how to protect themselves.
