Senior US officials say the United States is pulling roughly 60 percent of its staff out of Cuba and warning American travellers not to visit because of "specific attacks" that have harmed US diplomats.
The officials say the US is ordering all nonessential staff in the embassy in Havana to leave, along with all family members. Only "emergency personnel" will remain.
The US is also warning American citizens they could be harmed if they travel to Cuba. A State Department travel warning will note that attacks on diplomats have occurred in hotels.
The officials say the US is halting visa processing in Cuba indefinitely. They say the steps will remain until Cuba can assure the US its diplomats are safe.
