The Trump administration has blocked Cuba’s health minister from attending a regional meeting of the World Health Organization in Washington. This comes as part of an increasing crackdown by the Trump administration on Cuba. Last week, the U.S. placed sanctions on former Cuban President Raúl Castro, along with his children, for supporting the Venezuelan government. The United States also recently expelled two Cuban diplomats assigned to the United Nations. Meanwhile, Cuba is facing a severe fuel shortage due to crippling U.S. sanctions.
