The extensive search for a missing 74-year-old Dutch tourist on the Greek island of Samos has been called-off and, unfortunately, the man has not been found.

The tourist was declared missing on Sunday afternoon after he set off for a hike in the area of Limnionas and Clima on the island and did not return.

The head of the search and rescue operation called off the search on Wednesday evening, in accordance with protocol, following an intensive operation on land and sea which had the support of helicopters, drones and search dogs, said

It is the third case in just a week in Greece where a tourist set off on a hike, during high temperatures, and did not return.

Currently search and rescue operations are also underway on the Greek island of Amorgos for an American tourist, and after many days of search, the famous BBC presenter Dr. Mosley was found dead on the island of Symi.

The Greek government has released several warnings about high temperatures and related health risks during the ongoing heat wave in Greece, and has modified the working hours of the public sector and even closed schools in many regions.

Later new video footage emerged showing the BBC presenter and physician Michael Mosley walking downward along rugged terrain on the small Dodecanese island of Symi before he collapsed and eventually died on the spot.

The video was shown on the Mega Channel program “Live News”, following a revelation by the Athens daily “To Nea”.
