Jan. 12 (UPI) -- Cuban President Miguel Díaz-Canel has responded harshly to public warnings issued by U.S. President Donald Trump as tensions between Havana and Washington escalated.

Trump issued an ultimatum on his social media platform saying there would be "no more oil or money" from Venezuela for Cuba and suggesting the island should "reach a deal before it is too late" -- a move aimed at pressuring the Cuban government to negotiate or change course.

Díaz-Canel replied on X.

In a series of posts Sunday, the Cuban leader rejected the U.S. warnings and defended the country's sovereignty.
