A tanker believed to be carrying Russian oil to Cuba diverted its course away from the island during the reporting window from 11:45 PM UTC on February 26 to 2:45 AM UTC on February 27, 2026, a development reported by Bloomberg that risks exacerbating the Caribbean nation's ongoing fuel shortages, according to a Bloomberg article shared on X by @business. The diversion comes amid Cuba's deepening energy crisis, with the tanker originally destined to alleviate shortages on the fuel-starved island, as stated in the Bloomberg report published on February 26, 2026. No specific details on the tanker's name, exact diversion timing within the three-hour window, or new destination were provided in the source. This development occurs separately from earlier Cuban government updates on a territorial waters confrontation, where four deceased were identified and the participant list rectified to ten, per a statement shared by journalist Jorge Castro on X during the prior reporting period.
