HAVANA: Cuba’s leader warned Monday of a “bloodbath” in the event of an American attack, while the US Treasury sanctioned Cuba’s main intelligence agency and top leaders as tensions spiked between the arch-foes. President Miguel Diaz-Canel stressed Cuba’s right to defend itself a day after US news site Axios reported that Havana had obtained over 300 military drones from Russia and Iran and is mulling using them against US targets.
