A powerful earthquake struck Greek islands early morning today, damaging buildings and a port, killing at least two people and causing more than 100 injuries, authorities said. The island of Kos was nearest to the epicentre and appeared to be the worst-hit, with two deaths and structural damage to older buildings. Minor damage — cracks in buildings, smashed windows and trashed shops — appeared widespread, according to city officials. "The rest of the island has no problem. It's only the main town that has a problem," Kos Mayor Giorgos Kyritsis told state-run Greek media. "The buildings affected were mostly old, and were built before the earthquake building codes were introduced." Rescuers were checking for trapped people inside houses after the quake struck in the middle of the night.
