Concern grew on Wednesday over what caused the death of 16-year-old Nika Shahkarami who had joined the protests in Iran, even as the Iranian judiciary rejected accusations that she had been killed by security forces.
Reports from Persian media based outside Iran have said that the grieving girl's family were not allowed to bury her body in her hometown, while two close relatives have also reportedly been arrested.
Her aunt Atash Shahkarami wrote on Twitter that Nika went missing after attending a protest in Tehran on Sept. 20.
Ten days later the family was told that she had been found dead.
Protests across Iran, matched by solidarity marches in other countries, erupted in mid-September over the death of Mahsa Amini who had been arrested by the notorious morality police in Tehran.
