At least five people have died and multiple others have been injured in a spate of road accidents across Iran and Brazil since Thursday, according to local authorities and emergency services. The deadliest single incident occurred on a rural road in eastern Iran, where three members of one family were killed in a head-on collision between a passenger car and a truck.

Iranian traffic police said the crash took place around 19:45 local time on Friday on a village road linking Arask and Raqqeh in Boshruyeh county, South Khorasan province. A Peugeot 405 carrying four relatives collided with a Benz lorry; the driver, his mother and his sister died at the scene, while the driver’s wife was seriously injured and taken to hospital. A preliminary assessment by police suggests one of the vehicles may have veered into the opposite lane, a factor that investigators say could be linked to the narrow carriageway, the absence of a physical median, or driver inattention. The exact cause remains under expert review.

In Brazil, a multiple-vehicle crash on the PR-445 highway near Londrina, in the northern part of Paraná state, killed two people on Friday evening. State highway police reported that a motorcycle collided head-on with a Fiat Punto in a section where overtaking is prohibited, before being struck by a GM Corsa travelling in the same original direction as the bike. A fourth vehicle, a Fiat Argo, then rear-ended the Corsa. The two occupants of the motorcycle — a 36-year-old woman and a man who has not yet been identified — died before rescue teams arrived. The three car drivers, aged 35, 49 and 50, were unhurt and breathalyser tests returned negative results for all of them.

Separately, a 19-year-old motorcyclist, Matheus Gabriel Vicentini Fávaro, remained in intensive care in Maringá on Friday night after his motorcycle struck the rear of a trailer on Avenida Guaiapó the previous morning. Medical sources described his condition as extremely critical, with multiple fractures and a traumatic brain injury. Local reports noted that sun glare may have reduced visibility at the moment of impact. The young man had been recovering from another serious motorcycle accident three months earlier. In Apucarana, also in Paraná, a woman riding an electric bicycle was injured after hitting the back of a pickup truck waiting at a traffic light; the driver, a physician, provided first aid before paramedics arrived.

On the same highway where the double fatality occurred, a further accident late on Friday night left a motorcyclist injured near Tamarana. Police said no witnesses were present when officers arrived, and the circumstances of the crash remain unclear. The rider was taken to Londrina’s university hospital. Across all incidents, authorities have confirmed that investigations are ongoing and that provisional findings do not yet establish definitive causes.
