Four people were killed on Friday after a horrifying 13-car collision on a highway in Saudi Arabia, caused by a dust storm that severely reduced visibility.

Local newspaper "Okaz" reported that the accident occurred on the Rein-Bisha highway.

Several injured individuals were transported to the Rein General Hospital emergency room by the Saudi Red Crescent after receiving initial medical aid.

The newspaper reported that injuries ranged from multiple fractures and internal bleeding to minor injuries. Some victims were also transferred to King Saud Medical City and Qawiyah General Hospital for further treatment. Seven individuals were admitted for ongoing medical care, while eight others were released after their conditions improved.

Saudi weather expert Waleed Al-Haqil warned about the potential for dust storms in the same region via his official account on the social media platform X.

"According to the American Meteorological Observatory, the Rein-Bisha highway, the Wadi Dawaser-Khamis Mushait highway, eastern Asir, eastern Baha, and eastern Taif will experience dusty winds over the next ten days," he wrote.

Al-Haqil advised drivers to use a "car front protector" and drive cautiously when encountering dust.
