An Iranian court has sentenced popular singer Amir Hossein Maghsoudloo, known as Tataloo, to death on appeal after he was convicted of blasphemy, local media reported on Sunday.

The Supreme Court accepted the prosecutor's objection to a previous five-year prison sentence for crimes including blasphemy, reformist newspaper Etemad reported online.

It said the case was reopened and this time the accused was sentenced to death for insulting the Prophet.

The report said the verdict was not final and could still be appealed.

The 37-year-old underground musician had been living in Istanbul since 2018 before Turkish police extradited him to Iran in December 2023.

He has been in custody in Iran since then.

Tatalu was sentenced to 10 years in prison for promoting "prostitution" and was accused of spreading "propaganda" against the Islamic Republic and publishing "obscene materials," among other counts.

The heavily tattooed singer, known for combining rap, pop and R&B, was previously touted by conservative politicians as a way to reach out to young, liberal-minded Iranians.

Tataloo also held a bizarre televised meeting in 2017 with ultra-conservative Iranian President Ebrahim Raisi, who later died in a helicopter crash.

In 2015, Tataloo published a song in support of Iran's nuclear program, which later surfaced in 2018, during Donald Trump's first US presidency.
