At least eight people were killed and 15 others injured on Sunday after a bus overturned on an intercity road in Iran’s southern Bushehr Province, according to Iranian authorities.

The accident occurred on a major roadway in the province, prompting an immediate emergency response from rescue and medical teams. The Iranian Red Crescent Society said six rescue units were dispatched to the scene shortly after the crash was reported.

Emergency workers provided first aid to survivors before transferring the injured to nearby hospitals and medical centers for treatment. Several of the wounded were reported to be in serious condition, though officials have not yet released detailed information about the victims’ identities.

Iran’s semi-official Fars News Agency reported that the bus was transporting employees affiliated with the South Pars Gas Company, one of the country’s major energy sector enterprises connected to the massive South Pars gas field.

Images circulating in local media showed rescue personnel working around the overturned vehicle as emergency crews attempted to secure the area and assist passengers trapped inside the wreckage.

Authorities have launched an investigation into the cause of the crash. Officials have not ruled out possible mechanical failure, driver fatigue, or road conditions as contributing factors.

Road accidents remain a major concern in Iran, where thousands of people are killed annually in traffic-related incidents. Experts have frequently pointed to factors such as aging transport infrastructure, speeding, and insufficient road safety measures as major causes of deadly crashes across the country. (ILKHA)
