According to the official, Turkey has closed the crossings on security grounds.
He added that the closure will create no problem for trucks and busses, while putting restrictions on local people.
Turkey has not set a time limit for the closure, he noted.
The closure followed armed clashes inside Turkish border a day earlier. The southeastern parts of Turkey have been in restive situations in recent months.
In the meantime, a number of Iranian busses have been stopped on their way to Turkey . In one incident the driver was killed by unknown men.
Also, the railroads connecting Iran to Turkey have been mined inside Turkish territory a couple of times in the past month.
Following the disturbances, Tehran called on Iranians to avoid traveling to Turkey by land as much as possible.
The Iranian rail transportation company Raja also announced August 25 that trains from Iran to Turkey and back are off until further notice.
It said the decision follows the reconstruction of railroads in Turkey, adding that the reopening of the railroad will depend on when Turkey announces the accomplishment of the reconstruction.
