UNITED NATIONS (AP) — United Nations Secretary-General Ban Ki-moon has joined the United States, the European Union and human rights groups in expressing concern over last week’s death of a detained Chinese human rights activist in a Beijing hospital.

Last month, Human Rights in China quoted Cao Shunli’s lawyer as saying she suffered from tuberculosis, liver disease and other conditions and was not receiving proper medical treatment. China’s Foreign Ministry has denied that she died because of a lack of medical care.

U.N. deputy spokesman Farhan Haq said Wednesday that Ban shares the “deep concern” of human rights chief Navi Pillay that Cao was detained for seeking to allow the public to contribute to a report reviewing human rights in China for the U.N. and saddened at her death Friday.
