The about 70 heavy haulers carrying tangerines, that reached Nizhny Zaramag checkpoint in late December, remain there, a source in North Ossetia\'s law enforcement services told Interfax on Saturday. Most of the drivers are from North Ossetia. They are transporting tangerines from Georgia to Russia, but their journey was cut short by Russia\'s Veterinary and Phytosanitary Oversight Service Rosselkhoznadzor over a ban on fruit imports from Georgia. \"We\'ve lost 70% of the cargo and we\'ll continue the blockade of the Trans-Caucasus motorway until we are cleared into Russia,\" a driver told journalists. Many drivers have developed health problems in the absence of water, food and medicines, he said. North Ossetia\'s authorities are making efforts to persuade the drivers to cancel the blockade, a source in North Ossetia\'s law enforcement services said. (Interfax-South)
