Turkey has handed over to Iran a popular Iranian social media figure, Milad Hatami, accused by Tehran of money-laundering and fraud in connection with online gambling, a senior Iranian police official said on Tuesday.
Turkish officials did not immediately comment on the reported extradition.
Iran has been cracking down on online gambling and betting sites, which are illegal under the country's Islamic laws and have also been accused of money laundering. Iranian media said last week that the central bank had identified 450,000 bank cards used on the websites.
Regional powers Iran and Turkey have grown closer under Turkish President Tayyip Erdogan despite sometimes deep differences, including in Syria where they back opposing sides in the 10-year-old conflict.
But the two neighbors' ties have not been without strains.
Last month, Turkey arrested an Iranian official suspected of instigating the 2019 killing of an Iranian dissident in Istanbul, sources familiar with the matter said.
In December, Turkish officials accused Iranian authorities of targeting another opponent in Istanbul when they announced they had detained 11 people involved in the abduction and smuggling to Iran of an Iranian dissident wanted in connection with a deadly attack in southwestern Iran.
