US sanctions are 'collective punishment,' says Cuba during May 1 marches
Trump has mused about taking over Cuba, which lies 145 kilometers (90 miles) from Florida and has been under a nearly continuous US trade embargo since Fidel Castro led a communist revolution in 1959.
In an executive order on Friday, the US leader said he would impose sanctions on people involved in sweeping sections of the Cuban economy, which is steered by the government.
The latest sanctions constitute "collective punishment" of the nation's people, Cuban Foreign Minister Bruno Rodriguez said.
