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 the 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 explosion came at a tense moment for Iran after the US deployed an aircraft carrier group to the region following bellicose rhetoric from President Donald Trump.
