HAVANA: Two Mexican-flagged ships loaded with humanitarian aid entered Havana Harbor early on Thursday, a Reuters witness said, as Cuba’s long-time ally made good on a promise to assist after Washington threatened tariffs on countries that send oil to Cuba.

One of the ships, the ‌Papaloapan, carried large ‌quantities of white-wrapped pallets on its ​deck ‌as ⁠it ​passed beside ⁠the El Morro castle before entering the quiet waters of the harbor.

The shipment from Mexico arrives just days after the island’s communist-run government announced increasingly strict rationing measures to confront US efforts to cut off Cuba’s fuel supply.

Washington in January threatened tariffs on countries that supply oil ⁠to the island, saying that Cuba poses ‌an “extraordinary threat” to US national ‌security — a claim Havana denies.

Mexico announced ​the aid delivery after ‌halting shipments of crude and refined products to Cuba in ‌mid-January under pressure from the Trump administration.
