Police not to blame for Amini death:Iran

"The medical examinations and those of the forensic department show that there was neither beating (by the police) nor a fractured skull," Interior Minister Ahmad Wahidi said on Saturday, according to the Irna news agency.

He warned against what he described as false interpretations of the incident.

Amini's father strongly criticised the medical report into her death. His daughter did not have any heart problems and therefore could not have died of heart failure, he said.

Amini was arrested on September 13 for violating the strict Islamic dress code.

She fell into a coma and died in hospital days later, but it is unclear what caused her death, which triggered protests and unrest throughout Iran.

Critics accuse the morality police of using violence. The police reject the accusations.

Since then, hundreds of thousands of people have been demonstrating across the country against the government.

Earlier on Saturday, Iranian intelligence service said it had foiled several bomb attacks during the wave of protest.

According to an intelligence report published by the Mehr news agency, the attacks were planned by supporters of the former monarchy and militia members in the city of Tabriz in the north-west of the country.

Despite restrictions on internet access including mobile internet, there were unconfirmed reports of more demonstrations against the country's Islamic system overnight.

Some reports say as many as 35 people have died during the protests.

Iran claims that the demonstrations are controlled by foreign countries and Iranian exile groups in order to weaken the country or even overthrow the government.

"Protests yes, riots no," said President Ebrahim Raisi.
