The Nobel Peace Prize laureate and Iranian human rights activist Narges Mohammadi was violently beaten by prison guards last week, and her requests for hospital care and a meeting with her lawyer have been denied, her lawyer said on Thursday.

The lawyer, Mostafa Nili, told Iranian news media about the violence against Ms. Mohammadi, raising concerns about the state of her health and well-being. He said that her cellmates had communicated her situation.

“My client says that she was beaten and has bruises on her body,” Mr. Nili was quoted as saying in the reformist-leaning Emtedad news outlet. “Despite the prison doctor’s orders, and considering my client’s heart condition,” he said, “she has not been sent to the hospital.”

Mr. Nili said that for the past nine months, the prison authorities had denied Ms. Mohammadi the right to make phone calls and to have visits with her family and lawyer.

Ms. Mohammadi, 52, Iran’s most prominent human rights and women’s rights activist, is serving a 10-year sentence in the notorious Evin prison on charges of threatening national security because of her human rights advocacy. She was awarded the 2023 Nobel Peace Prize.

From the women’s ward of the prison, she has organized workshops, talks, protests and sit-ins against the government’s human rights violations.
