A powerful earthquake hit Turkey and Greece on Friday, killing at least six people, levelling buildings and creating a sea surge that flooded streets near the Turkish resort city of Izmir. Greek public television said the quake also caused a mini-tsunami on the eastern Aegean Sea island of Samos, damaged homes and injured at least four people. The US Geological Survey said the 7.0 magnitude quake was registered 14 kilometres (almost nine miles) off the Greek town of Karlovasi on Samos. The Turkish government's disaster agency reported a lower magnitude of 6.6 for the quake while Greece's seismological agency said it measured 6.7. Watch the video for more details.
