The US government also designated Abelardo Jimenez Gonzalez and Roberto Legra Sotolongo, who is Deputy Chief of the General Staff Revolutionary Armed Forces, the notice said on Thursday.
The Treasury Department said in a separate press release that it sanctioned the three persons in response to the recent violence the Cuban government inflicted on peaceful demonstrators.
“Today’s action exposes additional perpetrators responsible for suppressing the Cuban people’s calls for freedom and respect for human rights,” Treasury Department Office of Foreign Assets Control Director Andrea Gacki said.
The US government accused Legra Sotolongo of deploying a military police unit against protesters, the release said.
Gonzalez Brito was designated for leading the Central Army, which is already under US sanctions, while Jimenez Gonzales is responsible for the treatment and disposition of people imprisoned in Cuba, the release added.
Cubans rallied in the streets demanding improved economic conditions, as the island nation is going through hard times due to the tightening of the US economic embargo. The US government has accused the Cuban authorities of oppressing the country's opposition and restricting access to information, including during the recent protests in July.
In response, Havana said that Washington has no right to make any statements regarding demonstrations in the Latin American country.
The administration of former US President Donald Trump intensified the trade embargo in place on Cuba since 1962 by adding 243 new coercive measures against the Cuban government over four years that remain in effect to this day.
