A powerful undersea earthquake has shaken the Greek island of Crete.
The European-Mediterranean Seismological Centre said the 6.0-magnitude quake, which struck on Wednesday morning, was recorded at a depth of 56 kilometres between the islands of Crete and Kythera.
Tremors were felt on the southern parts of mainland Greece.
There were no immediate reports of damage.
It comes after a 6.4-magnitude earthquake and a 5.4-magnitude earthquake hit the Balkans within hours of each other on Tuesday.
At least 16 people were killed and 300 injured as the most powerful earthquake in decades struck Albania.
The 6.4-magnitude tremor hit in the early hours of Tuesday, causing several buildings to cave in and burying residents in the rubble.
The country’s defence ministry said a man and a woman were killed when a building collapsed in Thumane, 22 miles north of the capital Tirana.
Another man died after jumping from his home to escape the shaking building in Kurbin, 30 miles north of the capital, Albanian officials confirmed, while three more victims were pulled from the ruins of a building in Durres.
One of those killed was an elderly woman who saved her grandson by cradling him with her body, according to emergency workers.
Some 10 million people in Montenegro, Italy, North Macedonia, Greece and Bulgaria also felt the tremor when it struck at 3.55am, seismologist Branko Dragicevic told local media in Serbia.
Just hours later, at around 9.45am, a 5.4-magnitude quake shook neighbouring Bosnia. There are no immediate reports of injuries or structural damage.
The devastating Albanian earthquake, was centred 19 miles northwest of Tirana, with the worst of the damage reported in the Adriatic coastal town of Durres.
Dramatic video posted to social media from the town showed at least one large building there reduced to rubble.
