``We are fighting for justice,'' said a Muslim woman in a head scarf who, like others, said she was afraid to give her name.``They call this a democracy but they won't even let us gather and sit on a hillside.''

The women left after two hours when riot police trucks and a water cannon arrived. They did not mention Anwar but sang patrioticsongs.Anwar was brought to the University Hospital in a suburb outside the city on Saturday under heavy security, AFP said earlier, quoting the Sunday Star newspaper.

Police had sealed off the floor where Anwar was being examined by an orthopaedic surgeon and no visitors, including his family, were allowed, the daily said.

``Anwar is being treated like any other ISA detainee who cannot have visitors,'' the daily quoted a police official as saying. Anwar is being held under the draconian Internal Security Act which provides for detention without trial.

Health Minister Chua Jui Meng confirmed the medical examination on Anwar on Saturday saying a report would be submitted to the court.
