Turkey's Disaster and Emergency Management Authority (AFAD) said an earthquake took place in the Mediterranean Sea off southwestern Turkish shores on Tuesday.
In a Twitter post, AFAD said: ""#EARTHQUAKE: An earthquake with a magnitude of 5.4 occurred at 18.38 [1538 GMT] in the Mediterranean Sea off [southwestern] Marmaris shores."
The disaster agency said it was following developments.
Turkey has been hit by a series of earthquakes since the start of 2020 as a 5.4-magnitude quake jolted western province of Manisa last Wednesday and capital Ankara was rattled by a 4.5-magnitude quake on Thursday.
The worst of the quakes took place last Friday when eastern Elazığ province was hit by a 6.8-magnitude earthquake which led to death of 41 people and injury of some 1,600 others. The tremors were also felt in neighboring countries, including Georgia and Syria.
