ANKARA, May 27 (Reuters) - An earthquake of 5.1 magnitude hit Turkey's Manisa province east of the Aegean coastal city of Izmir on Saturday, broadcaster CNN Turk said, adding that initial reports showed no casualties or damage.

The earthquake hit the Saruhanli district of Manisa at a depth of 10 kilometres (6 miles) and the effects were felt in neighbouring towns and cities as well, it said.

Kerem Kinik, the head of Turkey's Red Crescent relief organisation, said on Twitter that the disaster coordination centre was carrying out evaluations. Turkey's Disaster and Emergency Management Presidency (AFAD) said the quake had struck at 16:53 GMT.
