Two strong earthquakes have rocked western Turkey, causing terrified residents to flee from their homes.
Some residents in Izmir are afraid to go back indoors
The first quake with a magnitude of 5.7 struck at 0545 GMT and was centred in the Aegean Sea off the city of Izmir, Turkey's Kandilli Observatory said.
It was followed by another undersea tremor with a magnitude of 5.9 at about 0947 GMT, the observatory said.
The quakes - felt also in Greece - caused minor damage. There were no immediate reports of injuries.
In villages along the coast local media reported cracks in buildings and collapsed chimneys. Residents are putting up tents in their gardens in the anticipation of aftershocks.
In Izmir - Turkey's third largest city - large crowds of people are still out in the streets, the BBC's Sarah Rainsford in Istanbul says.
After two serious shakes in quick succession they are afraid to go back inside, our correspondent says.
The local governor has called a crisis meeting and all schools in the province have already been closed and universities evacuated.
Small and moderate quakes are an almost daily occurrence in Turkey, which is criss-crossed by seismic fault lines.
More than 20,000 people were killed by an earthquake in north-western Turkey in August 1999.
