In mid-November, the oil tanker "Alithini II" sets off from Lagos, the capital of Nigeria, on a voyage to Las Palmas. What no one suspects at this point: Even three stowaways manage to ride along in an adventurous way.

On their flight to Europe, three stowaway migrants hid next to the rudder of an oil tanker for eleven days. According to the Spanish Coast Guard, they were spotted upon arrival in the Canary Islands. The three migrants were "located in the rudder blade of the ship 'Alithini II'" when it anchored near the port of Las Palmas, the Spanish Coast Guard said.

The authorities did not provide any information about the origin of the rescued. "They were tired and showing signs of hypothermia and upon arrival at the port they were treated by health services," the statement said. The rescued were "moderately dehydrated" and needed hospital treatment, wrote the emergency number 112 on Twitter.

According to tracking website shipfinder.com, the Maltese-flagged "Alithini II" took off from Lagos, the capital of Nigeria, on November 17. On Monday, the oil tanker arrived at the port of Las Palmas in the Canary Islands, off the northwest coast of Africa.
