Two Cuba-bound Relief Vessels Declared Missing after Setting Sail from Mexico.

A large-scale search and rescue mission is presently ongoing in the Caribbean waters for a pair of missing sailing vessels loaded with aid cargo journeying from Mexico to Havana.

Maritime Search Missions Launched

Authorities in Mexico has sent naval teams and reconnaissance aircraft to locate the two vessels, which were carrying no fewer than 9 sailors, per a navy statement.

The boats had been expected to make landfall in Havana on the early part of the week, but there has been radio silence from them and no official word of their safe arrival, the navy said.

The Situation of Aid to the Nation

The Caribbean nation has leaned on humanitarian shipments from Mexico over the past few weeks, as the nation struggles through repeated national electricity failures.

"The skippers and their teams are experienced sailors, and the two ships are equipped with appropriate navigational gear and communication devices," a representative for the convoy said.

The nine-person crew are nationals of Poland, France, Cuba and the US. Officials said it has been in touch with maritime rescue coordination centres from the involved countries along with their consular staff.

"The group is co-operating fully with the officials and continue to be hopeful in the crews' ability to make it to Cuba without incident," the spokesperson added.

Recent Aid Shipment

Previously that week, the Cuban authorities publicly celebrated and officially received another boat that had carried 14 tons of humanitarian aid to the island.

That vessel, nicknamed "a modern Granma" following the name of the boat in which Castro came back to Cuba to start the Cuban Revolution in the 1950s, carried photovoltaic panels, drugs, baby formula, bicycles and foodstuffs.

Larger Geopolitical Backdrop

Charity groups and individuals have primarily led attempts to deliver essential supplies to Cuba starting at the turn of the year, a period which saw a oil sanctions on the country came into effect.

Global bodies have since highlighted "dire" lack of essential goods, with over 50,000 operations called off in Cuba due to power shortages.

Foreign policy tensions have intensified lately, with remarks from various leaders emphasizing the delicate state of bilateral relations.

Responding to recent comments, a high-ranking Cuban official stated firmly that "the governance model of Cuba is not up for negotiation."

Accounts suggest that preliminary steps of negotiations had begun, although their present status remains uncertain.

The Mexican navy said it was committed to using the full extent of its capabilities at its disposal to find the vessels and secure the security of the sailors.

To date, there has been no public statement on the missing boats by the government in Havana.
