Greek police say a boulder dislodged from towering volcanic cliffs on the resort island of Santorini has killed an American tourist and injured four foreign women.
A police statement says the 52-year-old man was hit as he was riding a hired mule on the steep cobbled path winding down to the sea from Oia village _ a popular tourist destination on the brim of the island's trademark crags.
The cause of Monday's landslide was unclear.
The police statement said the victim's wife and daughter, as well as two Mexican women, were injured and were being treated on the Aegean Sea island. It did not name any of the tourists.
Santorini mayor Anastasios Nikolaos Zorzos told private Skai TV landslides are unusual on the island. He said a geologist would check the area.
