A total of 10 Turkish sailors kidnapped in Nigerian waters last month have been released on Saturday, Anadolu news agency said.
All Turkish sailors sailors, described by Anadolu as being in good health, were captured by a group of armed men who attacked the Turkish Paksoy-1 cargo ship under the control of the shipping company Kadioglu Denizcilik.
No further information has been received so far regarding the release of all prisoners.
A company citing Turkish media reports last month said the ship was attacked by pirates on its way from Cameron to the Ivory Coast.
It does not carry any load, however.
A group of pirates often make prisoners as captives for ransom.
The Nigerian government reported 14 pirate attacks in the first quarter of 2019 compared to 22 during the same period last year.
The International Maritime Bureau (IMB) reported in April that the decline in cases was contributed by the increasing efforts of Nigerian naval forces to act on every report received.
