Iran had alleged the Afghan truck drivers for smuggling fuel to Afghanistan, something Afghan drivers have denied and called it baseless.
A number of Afghan truck drivers protested at the Bandar Abbas border as the Iranian government had banned the entry of transit trucks bound for southwestern Nimroz province.
One thousand trucks were waiting to enter Afghanistan, causing a daily loss of 18 million AFN to the provincial customs department.
The restrictions are on transit vehicles with substandard fuel tanks; however, some protestors said their trucks had standard fuel tanks, but Iranian authorities had kept out vehicles stranded over the past 10 days.
One of the drivers, Amanullah, said he had to change the fuel tanks in order to gain back his passport and license from the Iranian authorities. He acknowledged that most Afghan trucks had sub-standard fuel tanks.
Over the past two weeks, the customs department suffered more than 240 million afghanis in losses, said the Director of Customs Ilhamuddin Mazhar
