Iran's supreme leader Ali Khamenei on Wednesday said "enemies" were involved in street violence that erupted last month over the death of Mahsa Amini.
Khamenei has already accused the United States, Israel and their "agents" of fomenting the unrest sparked by Amini's death after her arrest for allegedly failing to adhere to the Iranian republic's strict dress code for women, AFP said.
"Today, everyone confirms the involvement of the enemies in these street riots," Khamenei said Wednesday in a televised meeting with the Expediency Council, an advisory body.
"The actions of the enemy, such as propaganda, trying to influence minds, creating excitement, encouraging and even teaching the manufacture of incendiary materials, are now completely clear," he said, without identifying the enemy.
Earlier Wednesday, the judiciary said it had charged more than 100 people over the protests in Tehran and Hormozgan provinces.
"Some of these people are either enemy agents or... aligned with the enemy, and some are excited people," Khamenei said.
"The judicial and security authorities must do their duty" in dealing with the "enemy agents", he said.
Since September 16, dozens of people -- mainly protesters but also members of the security forces -- have been killed while hundreds of others have been arrested in several cities across the country.
On Wednesday, gunshots were fired as Iranian security forces confronted protests over Mahsa Amini's death in a crackdown that rights groups say has already cost at least 108 lives with many children among the dead.
The crack of gunfire interrupted demonstrators' chants in the cities of Isfahan and Karaj and in Amini's hometown Saqez, in videos shared by two Norway-based human rights organizations.
"Death to the dictator," shouted female students who had defiantly taken off their mandatory hijab headscarves as they marched down a Tehran street, in a video verified by AFP.
Shots were heard in Isfahan amid the "nationwide protests and strikes", Iran Human Rights (IHR) said of a video it tweeted, and in Saqez, according to the Kurdish rights group Hengaw, which reported that later "the security forces fled".
Amini, 22, died on September 16 after falling into a coma following her arrest in Tehran by the notorious morality police for an alleged breach of the Iranian republic's strict dress code for women.
Young women, university students and even schoolgirls have since taken off their hijabs and faced off with security forces in the biggest wave of social unrest to grip Iran in almost three years.
At least 28 children have been killed and hundreds more detained and held mostly in adult prisons, rights groups said.
Deadly unrest has rocked especially Sanandaj in Amini's western home province of Kurdistan -- but also Zahedan in Iran's far southeast, where demonstrations erupted on September 30 over the reported rape of a teenage girl by a police commander.
'Bloody crackdown' feared -
Activists in Tehran called for protesters to turn out "in solidarity with the people of Sanandaj and the heroic people of Zahedan".
"We don't want spectators. Come and join us," a group of mainly young women outside Tehran's Azad University sang in IHR footage verified by AFP.
The protest slogan "Woman, Life, Freedom" was spray painted on the wall of the former US embassy -- abandoned in the wake of the 1979 Iranian Revolution and subsequent hostage crisis -- but later painted over, an image obtained by AFP showed.
A man who asked not to be identified told the BBC: "The atmosphere is quite tense and yet it is exciting. People are hopeful this time and we hope that a real change is just around the corner. I don't think people are willing to give up this time.
"You can hear some sort of protest everywhere, almost every night. That feels good, that feels really good."
IHR said the security forces had so far killed at least 108 people, and at least another 93 people in Zahedan, while warning of an "impending bloody crackdown" in Kurdistan.
It also said workers had joined protest strikes this week at the Asalouyeh petrochemical plant in the southwest, Abadan in the west and Bushehr in the south.
In its widening crackdown, Iran has blocked access to social media, including Instagram and WhatsApp, and launched a campaign of mass arrests.
- Missing children -
EU countries on Wednesday agreed punitive measures on Tehran.
European Commission chief Ursula von der Leyen said it was "time to sanction those responsible" in Iran "for the repression of women", while French President Emmanuel Macron expressed solidarity with the protesters.
The Tehran-based Children's Rights Protection Society, which reported the deaths of 28 minors, condemned security forces for violence against children.
It criticized "families being kept in the dark on their children's whereabouts, cases proceeding without lawyers and a lack of children's judges and police".
Revolutionary Guards deputy commander Ali Fadavi told Iranian media on October 5 that the "average age of the detainees from many of the recent protests was 15".
On Twitter, Canada's foreign minister slammed Iran for killing child protesters.
"Canada condemns the Iranian regime’s continued use of violence against protestors, resulting in the death of civilians, including children," Melanie Joly wrote. "The ongoing arbitrary detention and mistreatment of protestors must stop."
Human rights lawyer Hassan Raisi said around 300 people between the ages of 12 and 19 were in police custody, some of them in detention centers for adult drug offenders.
Iran's judiciary said more than 100 people had been charged in Tehran and Hormozgan provinces alone.
An official Iranian forensic investigation found Amini had died of a longstanding illness rather than reported beatings.
Her parents have denied this and filed a complaint against the officers involved. A cousin living in Iraq has told AFP she died of "a violent blow to the head".
