Two French tourists, aged 64 and 73, disappeared Friday after walking on the Greek island of Sikinos, according to Vasilakis, who said police did not know exactly where they were walking or what their destination was. One of the tourists sent a distress message to the guesthouse where she was staying, which then alerted Greek police, Vasilakis said.

Key context

Other tourists were found dead or missing in Greece last week. A 55-year-old American tourist was found dead on the Greek island of Mathraki on Sunday, three days after being reported missing by a friend with whom he was staying. Greek authorities will conduct an autopsy to determine the cause of his death, Mathraki officials told ABC News. A 74-year-old Dutch tourist was found dead on the Greek island of Samos on Saturday, according to the Associated Press. Greek authorities found the tourist lying face down in a ravine about 300 meters from where he was last seen a week earlier. Three other tourists, an 80-year-old Belgian, a 70-year-old French woman and a 70-year-old Dutch man, died Friday while hiking in Crete, Greek officials told the New York Times. Michael Mosley, a former British television presenter, was found dead earlier this month on the Greek island of Symi. Mosley, 67, took the wrong route while hiking and collapsed where his body was not easily visible, his wife said.

Tangent

Greek authorities have issued warnings as temperatures continue to rise across the country, including temperatures reaching 112 degrees on the island of Crete. The Acropolis in Athens was closed to tourists last week as temperatures reached 104 degrees.
