At least six people were killed and several others injured in separate explosions in southern and southwestern Iran, local media reported on Saturday.

According to Mehr News Agency, the blast occurred at a four-unit residential complex in the Kianshahr neighborhood of Ahvaz in southwestern Iran, killing five people due to failure to observe safety precautions.

The Ahvaz Municipality Fire Department and Safety Services said the explosion was caused by a leak in the city's gas network.

Separately, an unknown substance exploded in an eight-story building located in an alley off Moallem Boulevard in Bandar Abbas, southern Iran, according to the Fars news agency.

A four-year-old girl was killed in the explosion, and about 14 other people were injured.

More than 10 vehicles parked near the building were also damaged to varying degrees.
