New Delhi, Nov. 15 -- Cuban President Miguel Diaz-Canel has warned that the island is preparing to repel foreign military aggression amid rising tensions with the Trump administration. Speaking during defence activities in Havana, he pointed to nationwide military exercises and intensified civilian preparations. Diaz-Canel demanded an end to U.S. pressure and the long-standing blockade, insisting that Cuba poses no threat to other nations. His remarks come as tighter oil restrictions and sanctions deepen the country's energy crisis and hardship for ordinary Cubans.
