Frankfurt - Tehran
Our gate to Persia was Frankfurt Airport. Even though the airplane of IranAir already is Iranian ground we were not forced to wear a headscarf.
According to the last census in 1992 Teheran had 7 mio. inhabitants - the real number today must lie somewhere between 14 and 15 mio.
We only stayed one night at Tehran. Later we got informed that all the phone lines out of the hotels are tracked.
