KOS, Greece - At least two people were killed and more than 120 injured early Friday when a powerful earthquake rocked a Greek island and resorts on the southwestern Turkish coast, triggering a small tsunami.

The magnitude-6.7 quake struck 6 miles south of the Turkish city of Bodrum and 10 miles from the Greek island of Kos. Both areas are popular with holidaymakers from around the world.

Two tourists, from Turkey and Sweden, died in Kos, Greek authorities said. At least 20 people were injured and buildings were damaged. The tsunami caused localized flooding on the island.

Greece and Turkey lie in an area with fault lines and are prone to earthquakes.

Kos Mayor Giorgos Kyritsis said a wall on a 1930s building collapsed, crushing people at a bar, the Associated Press reported.

“There are not many old buildings left on Kos. Nearly all the structures on the island have been built under the new codes to withstand earthquakes,” Kyritsis said.

Regional governor Giorgos Hadjimarkos added that four or five of the casualties had “worrying” injuries and the “main priority at the moment is saving lives.” Hospital officials said at least 20 people had broken bones.

Esengul Civelek, the governor of Mugla province in Turkey, said some people there suffered minor injuries.

Christopher Hackland, from Edinburgh in Scotland, works as a scuba instructor on Kos and lives in an apartment next to a hotel.

“There was a lot of screaming and crying and hysterics coming from the hotel,” he told the AP. “It felt like being at a theme park with one of the illusions, an optical illusion where you feel like you’re upside down.”

Turkey’s disaster and emergency management authority said there were a number of aftershocks in both countries.
