JOHANNESBURG, June 21 (Xinhua) -- South African police on Thursday arrested 62 people for blocking the roads to protest against the employment of foreigners as truck drivers.

KwaZulu-Natal police said they also impounded 51 trucks used to block the busy N3 freeway between Durban and Johannesburg.

"We have laws in this country and the full might of the law will be heard and felt," said the Police Minister Bheki Cele, adding that the arrested drivers were charged with public violence and obstructing traffic.

"Police action will be very tough in maintaining law and order. This barbaric behavior will not be tolerated," he added.

The minister said the government is willing to engage those drivers who follow the right channel.

The freeway was cleared in the afternoon.
