Twenty-five Iraqi tourists were killed and 16 injured when their bus plunged off a cliff in Iran's northern mountains on Tuesday.
A brake defect caused the driver to lose control, sending the bus crashing 200 metres (650 feet) down into a river in the Alborz mountain range.
Authorities were still searching for one body, which might have been carried away by the river, a provincial crisis response official was quoted as saying.
The Iraqis were on their way to a Caspian Sea resort.
