Iran on Wednesday called for the immediate release of an American-born journalist arrested in the United States while working for Iran’s English-language state television, accusing Washington of mistreating her in jail as a black Muslim woman.

Iran’s English-language Press TV said earlier Wednesday that Marziyeh Hashemi, its TV anchor and documentary film maker, was arrested at St. Louis Lambert International Airport on Sunday and was being held in Washington. She has not been formally charged.

Federal Bureau of Investigation officials were not immediately available for comment.

“We condemn the illegal arrest of Marziyeh Hashemi, the reporter and presenter of Press TV, and the inhuman treatment of her in jail in Washington,” Iranian Foreign Ministry spokesman Bahram Qasemi was quoted as saying by state news agency IRNA.

Press TV said in a statement on its website that Hashemi “a mother and a grandmother … has traveled to the United States to visit her family members, including her brother, who is suffering from cancer.”

She was allowed to call her daughter two days after her arrest, the broadcaster said.

According to Press TV, Hashemi was born Melanie Franklin in the United States and changed her name after converting to Islam.

She was quoted as saying by Press TV that she had been prevented from wearing a hijab, a head covering worn in public by some Muslim women, in prison, and was only offered pork as a meal, which is prohibited in Islam.

The only food she has had over the past two days has been a “packet of crackers,” Hashemi was quoted as saying by Press TV.

Reuters could not independently verify the account of her treatment.

“The sudden arrest of an American Muslim woman, and inhuman and disrespectful behavior of US federal officers with her is a clear example of how an apartheid regime treats its non-white citizens,” Qasemi said.

Hashemi has lived in Iran for more than a decade, according to various Iranian media.

She has reported on the subject of discrimination against women, Muslims, and African-Americans in the United States.
