At least two people have been killed and more than 100 have been injured after a strong earthquake struck Greek islands and Turkey’s Aegean coast early Friday morning, authorities said.

Buildings on the Greek island of Kos sustained structural damage from the earthquake, the city’s mayor, Giorgos Kyritsis, told state-run Greek media.

"The buildings affected were mostly old and were built before the earthquake building codes were introduced," Kyritsis said.

The coast guard announced the island's port was part of the structural damage.

According to Turkish disaster officials, more than 20 aftershocks have been recorded.

The BBC reported a small tsunami occurred on the Turkish coast.

Greece and Turkey lie in an especially earthquake-prone zone.
