Ten of the dead were women, the ISNA news agency said, adding that the accident happened on Sunday night in western Iran, between the Shia shrine city of Qom and the Iraqi border.
"Because of the rain, the high speed and the driver's inability to control the vehicle on the slippery road, the vehicle overturned," ISNA quoted a police official as saying.
Iran's Shia holy sites draw many Iraqi pilgrims. The country's road safety record has improved in recent years but it still averages around 20,000 road deaths a year.
