Protests have broken out in several Iranian cities over the death of a young woman, who died at hospital a few days after collapsing at a police station in the capital Tehran, where she and a group of others were receiving educational training on dress code rules.
Protests were reported in Mahsa Amini�s hometown of Saqqez, Tehran, and a number of other cities.
The protesters demanded clarification on circumstances surrounding the death of the 22-year-old woman.
Some protests have turned violent, leading to attacks on police and acts of vandalism.
On Monday, Commander of Greater Tehran Police�Brigadier General Hossein Rahimi�dismissed �coward accusations��that Amini was violently assaulted in custody.
�The incident was unfortunate for us and we wish to never witness such incidents,� the police chief said during a press briefing.
Rahimi said �false accusations� had been made against the Iranian police and that Amini was not harmed physically during and after she was taken into custody.
He added the police had �done everything� to keep her alive.
Iranian police on Friday released CCTV footage, which shows Amini collapsing in the�police station.
The video rejected claims that she was beaten up, denying any physical contact against her.
Dr. Massoud Shirvani, a neurosurgeon, told IRIB TV2�television channel on Tuesday that the deceased woman had a brain tumor removed at the age of 8.
