Protests broke out on the streets of Yazdanshahr, in Isfahan province in central Iran, on Tuesday, with gunfire heard, according to videos sent to Iran International.
The footage shows security forces bringing military-style vehicles into the streets as protesters gathered.
Security forces were attacking and beating people, according to an eyewitness account.
In another video from the city, women are heard chanting: “Free those detained in Yazdanshahr.”
Security forces closed the entrance to Sina Hospital in the Hasanabad area of Tehran on Tuesday, with sounds of gunfire heard nearby, according to a video received by Iran International.
The footage showed protesters running in surrounding streets and chanting slogans, including “Death to the dictator,” according to the video.
Amnesty International condemned Iranian security forces over an attack on a hospital in the western city of Ilam, calling it a violation of international law.
The rights group said security forces targeted Imam Khomeini Hospital, where injured protesters were seeking treatment or shelter, adding that the actions showed “how far the Iranian authorities are willing to go to crush dissent.”
Amnesty said forces fired tear gas, used shotguns, beat people inside the hospital and arrested injured protesters and some family members, urging authorities to “immediately stop the unlawful use of force” and respect medical facilities.

Iran’s government said it had ordered an investigation into unrest in the western province of Ilam after rights groups condemned reports that security forces raided a hospital where injured protesters were being treated.
Tensions in Ilam peaked this week after clashes between security forces and demonstrators in Malekshahi, a town near the Iraqi border, where forces fired live rounds to disperse protesters, killing several people and injuring dozens.
The situation escalated late on Sunday when security forces entered Imam Khomeini Hospital, where wounded demonstrators had been taken for treatment, according to rights groups.
Amnesty International said on Tuesday, “The Iranian security forces’ attack on a hospital in Ilam, where injured protesters are seeking medical care or shelter, violates international law.”
The rights group said information it gathered showed that on January 4, Revolutionary Guards and police special forces surrounded the hospital, used shotguns and fired tear gas into the grounds, smashed glass doors to gain access, and beat those inside, including medical workers.
Amnesty cited informed sources as saying that security forces had entered the hospital on multiple occasions, arresting injured protesters receiving treatment and their family members.
Rights groups also said security personnel attempted to seize the bodies of protesters killed in the unrest to prevent public mourning ceremonies.
President Masoud Pezeshkian ordered the interior minister on Monday to assemble a team of relevant officials to examine the incidents in Ilam, the causes behind the unrest and how authorities responded, and to submit a comprehensive report to the president’s office as soon as possible, according to a government statement.
Shopkeepers in the city of Marvdasht in southern Iran closed their shops and joined a strike in support of nationwide protests, according to videos received by Iran International.
German parliament vice president Omid Nouripour said people in Iran were protesting because they wanted freedom and called on others to amplify their voices.
“People in Iran are taking to the streets because they want to be free. We must listen and strengthen their voices. It is now or never,” Nouripour wrote on X.
