Greek authorities say 12 Russian tourists have been injured in a lightning strike at the archaeological site of Knossos, on the southern island of Crete.
Health officials say one of the tourists, a 46-year-old woman, suffered a heart attack but was out of danger after being treated in hospital. The remaining 11 people taken to hospital had light injuries or were suffering from shock.
The accident occurred early Friday inside the ruins of the prehistoric palace of Knossos, near the port city of Iraklio in northern Crete. The injured people were part of a group of Russian tourists.
There were no immediate reports of damage to the ancient site, which is one of Greeces main archaeological attractions.
