Police said the tanker’s brakes failed, causing it to slam into the bus, AP news agency reported.

An official said at least nine people were injured in the crash.

Kurdistan province has declared three days of public mourning over the crash.

UNICEF said Iran’s rate of traffic crashes is 20 times the world’s average, as the country suffers from poor roads and lax traffic enforcement.

According to a May 2017 report by the Tehran-based newspaper, Financial Tribune, over 20,000 people are killed and 800,000 injured annually in road accidents in Iran.
