The U.S. military said Wednesday that it boarded an Iranian-flagged oil tanker in the Gulf of Oman that was suspected of trying to violate the American blockade, the latest action by the Trump administration to try to push Tehran to reopen the Strait of Hormuz.

The resulting fuel crisis has led to major power blackouts and triggered protests in Cuba. President Donald Trump has also put Cuba under significant pressure to "make a deal" and threatened its communist regime that the US could intervene like it did in Venezuela earlier this year when it captured President Nicolás Maduro.
