Tens of drivers of the Greater Tehran's Collective Buses were rounded up, today, in downtown Tehran. The drivers were intending to protest against their poor conditions and the arrest of several of their colleagues.

Tens of security agents and plainclothes men intervened immediately and arrested the demonstrators after filming the area and taking pictures from protesters.

Militia's Commander Jaffarzadeh was heard stating to the protesters: "You must end your gathering or I'll cut off your head!"

The protesters, who were composed of hundred drivers, were forced inside several special buses which left the scene for an un-identified location.

Official warning was made, earlier, against all drivers who are intending to quite work and to protest. Security agents were seen putting lock on the small and tolerated syndicate's office after taking away many materials, such as, computers and books.

Other drivers have issued a warning to the Islamic regime for the immediate release of all their arrested colleagues. Failure to do so would result in a general strike on Sunday early morning and a day of sit in, with road block, on the Vali-e-Asr avenue from its square till the Tehran's Train Station.

Security forces are expected to be in number and to crush any, such a, gathering especially in the main Capital's artery.
