WASHINGTON: An Iranian-American journalist sentenced to 10 years in a notorious Tehran prison called on Washington to provide medical help for him and other US detainees, CBS News reported Friday.

Reza Valizadeh, who holds both Iranian and US citizenship and worked for US-funded Persian-language Radio Farda, is in prison on charges of collaborating with a hostile government, according to his lawyer.

A voice message from the journalist obtained by CBS News comes amid a shaky truce as Tehran and Washington conduct slow-moving negotiations to resolve a war launched by President Donald Trump in February.

Valizadeh said in the two-minute recording that he and three other Americans held at Tehran’s Evin prison were sick and being denied medical treatment.

“While the four of us are suffering from various diseases and are deprived from real medical services, the US government could have at least demanded real medical services for us in exchange for the release of Iranian sailors,” he says.
