The Turkish truck drivers told Anadolu Agency Friday that they began leaving Duba Port on the country's northern Red Sea coast by evening.
Sixty trucks have left the port while the others will leave tomorrow, they added.
Noting that they experienced hard times in the country for 12 days because of the extremely hot weather, the drivers also said that one of their colleagues had fainted.
Turkey has been closely following the matter and Trade Minister Ruhsar Pekcan said she spoke with her Saudi counterpart by phone this week.
Turkey's embassy in Riyadh and consulate general in Jeddah also made intensive efforts to secure the passage of the trucks through customs as soon as possible.
