An explosion struck a building on Saturday in the Iranian Gulf coast city of Bandar Abbas, state media said, with the cause yet unknown.
State television said the explosion occurred at an eight-storey building, "destroying two floors, several vehicles, and shops" in the area of Moallem Boulevard in the city.
Rescue and firefighting teams were on site to provide assistance, it added.
The official IRNA news agency quoted the director general of crisis management in Hormozgan province, Mehrdad Hassanzadeh, as saying the cause of the explosion was under investigation.
"Those injured in the incident are being transferred to hospital by emergency responders," he added, without reporting any fatalities.
Images carried by state TV showed the building's facade blown out, exposing parts of its interior, with debris scattered around.
Other Iranian media carried similar reports, also without providing details on the cause.
The semi-official Tasnim news agency said that social media reports alleging that a Revolutionary Guard navy commander was targeted in the explosion were "completely false". The Islamic Revolutionary Guard Corps is considered the backbone of Iranian security and reports directly to Supreme Leader Ayatollah Ali Khamenei.
The explosion came at a tense moment for Iran after the United States deployed an aircraft carrier group to the region following bellicose rhetoric from President Donald Trump.
