And on the island of Samos, a 74-year-old Dutch tourist has been missing since Sunday, with a large search and rescue operation underway, authorities said.
The man had gone hiking in the Marathokampou area of the island, the Hellenic Rescue Team of Samos said on Wednesday.
Local residents are helping with the search, it added.
Konstantia Dimoglidou, a spokesperson for the Greek police, told CNN on Thursday that “police, fire brigade and volunteers are involved in the search, including by air,” for both men.
“Unfortunately, so far we have no news about either of them,” she added.
